shell_exec("Rscript C:\R\R-3.2.2\bin\code.R ");
This is the call to script.On calling the above script, the error occurs.
I am trying to call my R script from the above path but no output is being shown. While checking the error logs of PHP, it says 'Rscript' is not recognized as an internal or external command, operable program or batch file.' The script is working fine on the Rstudio but not running on the command line.
Add the Rscript path to your environment variables in Windows:
Go to Control Panel\System and Security\System and click Advanced System Settings, then environment variables, click on path in the lower box, edit, add "C:\R\R-3.2.2\bin"
Restart everything. Should be good to go. Then you should be able to do
exec('Rscript PATH/TO/my_code.R')
instead of typing the full path to Rscript. Won't need the path to your my_code.R script if your php file is in the same directory.
You need to set the proper path where your RScript.exe program is located.
exec ("\"C:\\R\\R-3.2.2\\bin\\Rscript.exe\"
C:\\My_work\\R_scripts\\my_code.R my_args";
#my_args only needed if you script take `args`as input to run
other way is you declare header in your r script (my_code.r)
#!/usr/bin/Rscript
and call it from command line
./my_code.r
If you are running it in Git Bash terminal, you could follow a revised version of the idea suggested by #user5249203: in the first line of your file my_code.R, type the following
#!/c/R/R-3.2.2/bin/Rscript.exe
I assumed that your path to Rscript.exe is the one listed above C:\R\R-3.2.2\bin. For anyone having a different path to Rscript.exe in Windows, just modify the path-to-Rscript accordingly. After this modification of your R code, you could run it in the Git Bash terminal using path-to-the-code/mycode.R. I have tested it on my pc.
I faced the same problem while using r the first time in VS Code, just after installing the language package (CRAN).
I restart the application and everything worked perfectly. I think restarting would work for you as well.

I'm trying to run an R script through the command prompt. My operating system is Windows 10. I'm having trouble running the code because there is a space in the file path of my argument. This is what I paste into the command prompt.
"C:\Program Files\R\R-3.4.3\bin\Rscript.exe" "C:\Users\Scott\Google Drive\RScriptsB\Bundle_Runner.R"
I get this error:
The filename, directory name, or volume label syntax is incorrect.
However, when I run it using a file path with no spaces, it runs fine.
"C:\Program Files\R\R-3.4.3\bin\Rscript.exe" "C:\Users\Scott\Desktop\Bundle_Runner.R"
The same behavior happens when I schedule the task through Task Scheduler: it doesn't work with the space, and it works when I remove the space from the file path.
I'm using Google Drive to sync work from multiple computers, so I'd like to be able to run my scripts using the file path with a space.
Any solutions?
FOR %%a IN ("C:\Users\Scott\Google Drive\RScriptsB\Bundle_Runner.R") DO "C:\Program Files\R\R-3.4.3\bin\Rscript.exe" %%~sa
would be my approach - the problem appears to be with R, not cmd.
Try this:
C:/PROGRA~1/R/R-3.4.3/bin/Rscript.exe "C:\Users\Scott\Desktop\Bundle_Runner.R"
Or
C:/PROGRA~1/R/R-3.4.3/bin/Rscript.exe C:/Users/Scott/Google~1/RScriptsB/Bundle_Runner.R
This is possibly related to an error reported at r-devel ("[Rd] Bug in RScript.exe for 3.5.0", https://stat.ethz.ch/pipermail/r-devel/2018-April/075869.html) that has been fixed the next day.
Perhaps the problem was already present in R 3.4.3 (you are using in your question).
Proposed workaround:
...add an extra first argument that has no space in it, e.g. Rscript --vanilla "foo bar.R"
To minimize the impact caused by --vanilla you could use
Rscript --no-save "foo bar.R"
instead (which just does not save the workspace at the end of the session).
I am trying to run a Windows executable file from R. I have managed to open the executable file from R using the command:
system2('cmd', args=c('/c', '"C:/Program Files (x86)/UIFormModel.exe"'))
To run the executable file, I need to import an Excel file by clicking on the button “Load Settings File” (see figure below). Thus, the button is part of the executable file.
How can I do this from R ?
I have tried this command but it does not work:
system2('cmd', args=c('/c', '"C:/Program Files (x86)/UIFormModel.exe"', '"F:/template_LHS1.xlsx"'))
'C:/Program' is not recognized as an internal or external command,
operable program or batch file.
Warning message:
running command '"cmd" /c "C:/Program Files (x86)/UIFormModel.exe" "F:/template_LHS1.xlsx"' had status 1
Several points:
normally one does not have .exe files directly under C:\Program Files (X86) so first double check the path name. I suspect it is not as in the question but is something like the one shown below.
note the quoting used below
are you sure that the program accepts a command line argument as an alternative to its GUI? Can you run it from Windows cmd line? If not you could write an autohotkey (see AutoHotKey section below) or autoit script to control it and launch that from R.
if it does accept an argument ensure that the program allows forward slashes -- if not use backslashes
cmd line argument accepted
If the program accepts a command line argument then try this code:
system2("C:/Program Files (x86)/UIFormModel/UIFormModel.exe", "F:/template_LHS1.xlsx")
Another way is:
shell('"C:/Program Files (x86)/UIFormModel/UIFormModel.exe" F:/template_LHS1.xlsx')
For example, using the free CSVfix I was able to run the following and found that they worked:
system2("C:/Program Files (x86)/CSVfix/CSVfix.exe", "help")
shell('"C:/Program Files (x86)/CSVfix/CSVfix.exe" help')
See ?system2 and ?shell for other arguments you may wish to use.
AutoHotKey
If the program does not accept command line arguments then this sample AutoHotKey script launches WinMerge, a free file comparison GUI for Windows, comparing the WinMerge executable to itself. This has the effect of generating a popup warning and the AutoHotKey script dismisses that warning message by sending an Enter keystroke to the WinMerge window.
Be sure AutoHotKey and WinMerge are installed, that the script below is in a text file, test.ahk, in the current directory, the one given by getwd(), and then from the R console run:
shell("test.ahk")
Here is the test.ahk script:
exe = "C:\Program Files (x86)\winmerge\winmergeu.exe"
Run %exe% %exe% %exe%
WinWait WinMerge
; dismiss the dialog warning that both files are the same
Send {Enter}
If you go this route this script will need to be modified or rewritten in ways that will be specific to your program.
I've been trying several alternatives, but I've not successfully called an executable with a parameter. Nevertheless I can suggest a workaround using a .bat file:
system2("cmd.exe", input='"D:/workspace/execute.bat"')
Where execute.bat may contain something like:
C:/Program Files (x86)/UIFormModel.exe F:/template_LHS1.xlsx
I'm trying to run a R script through a .bat file. When I run myself the commands line by line it works. But when I try to run the .bat file, it doesn't works.
This is the .bat file
cd "C:\Program Files\R\R-3.1.2\bin"
R CMD BATCH "C:\Users\Administrator\Downloads\testa_vps.R"
This is the R script
setwd('C:\Users\Administrator\Documents')
file.create('mycsv.csv')
I'm not an expert with Windows and generally try to stick to Unix-like systems for things like this, but I have found that using programs non-interactively (e.g. via .bat files) is usually less error-prone when you add the appropriate directories to your (user) PATH variable, rather than cding into the directory and calling the executable from within the .bat file. For example, among other things, my user PATH variable contains C:\PROGRA~1\R\R-3.0\bin\; - the directory that contains both R.exe and Rscript.exe - (where PROGRA~1 is an alias for Program Files which you can use in an unquoted file path, since there are no spaces in the name).
After you do this, you can check that your PATH modification was successful by typing Rscript in a new Command Prompt - it should print out usage information for Rscript rather than the typical xxx is not recognized as an internal or external command... error message.
In the directory C:\Users\russe_000\Desktop\Tempfiles, I created test_r_script.r, which contains
library(methods)
setwd("C:\Users\russe_000\Desktop\Tempfiles")
file.create("mycsv.csv")
and test_r.bat, which contains
Rscript --vanilla --no-save "C:\Users\russe_000\Desktop\Tempfiles\test_r_script.r"
Clicking on the Windows Batch File test_r ran the process successfully and produced mycsv.csv in the correct folder.
Before running test_r.bat:
After running test_r.bat:
I've never worked with a Windows server, but I don't see why the process would be fundamentally different than on a personal computer; you just may need your sysadmin to modify the PATH variable if you don't have sufficient privileges to alter environment variables.
As already suggested by #nrussel in the comments you should use RScript.exe for this.
Create a file launcher.bat with the following content:
cd C:\Users\Administrator\Documents
Rscript testa_vps.R
In addition, add C:\Program Files\R\R-[your R version]\bin\x64; or C:\Program Files\R\R-[your R version]\bin\i386to the System PATH variable in the Environment Variables menu depending if you run R on a 64-bit or 32-bit system.
I just tested the approach above successfully on a Windows Server 2008 64-bit system and mycsv.csv got created as expected.
EDIT
One important point I forgot to mention is the following: You need to specify the path in your R file in the setwd() call using \\ instead of \.
setwd('C:\\Users\\Administrator\\Documents')
Here is a screenshot of the successful run on the Windows 2008 server:
Note: I added cmd /k to the .bat file so that the cmd window stays open after clicking on the file.
I have an install.bat file and a resource folder. so long as these two files are in the same directory, if you run install.bat, it will install a my lwjgl game. so what im trying to do is make a self extracting file that when completed runs the launch.bat file. I have tried using iexpress, and got it working for the most part. i have added in all my files and such so it will extract to some directory and then i can run the install.bat file to get my program to work. thing is though, i want the exe i created with iexpress to launch install.bat when its finished. so, i tried using the option in iexpress that says it will execute a command when finished the "installation" (using quotes because its not the actual installation, just extracting the files to some directory specified by the user). when i get to the step where it says what i would like to execute during and after the "installation". during the installation i left blank. after the installation i chose the install.bat file. when i try to click next though, it tells me i must choose something for the command during the extraction. I don't have anything specific to do during the installation so i just said "echo." (without quotes). after i was done i tried running the installer. before it even prompted me for a folder to extract to, it told me that echo. could not be executed. so i went back into my installation (via a .sed file) and changed the "echo." to "pause". that didn't work either. i then read on another website that in order to run a file the way i would like to, i put the file name in both the during and after installation boxes. i tried doing that and it didn't work either. can anyone please help me?
If I understood your question correctly you will need to specify what the iexpress must do at the post install command option provided so that cmd.exe is used instead of command.com, eg:
cmd.exe /c filethatyouwanttorun.bat
Refer to the question: Create Batch file for iexpress.
You can use the SED file and then modify the self extraction directive. This will run the batch file that you wanted to run and then install the application. (If you have chosen the option to extract and run an installation in iexpress, a temp folder will be used for the extraction I suppose.)
I'm not sure I understand your question exactly but perhaps a few points would help:
If you want a "do nothing" command, you can use something like:
cmd /c echo.
There is no "command during the extraction". There's only an install program and a post install command. Both of these execute after extraction. If you only need to execute one batch file, put it in the install program line and leave the post install command blank.
You can't ask the user for an extraction path and execute a file. You can only do one or the other. (The install program could prompt the user and copy the files there, though.)
I want to run a R script file (.r) using batch file.
If R.exe is in your PATH, then your windows batch file (.bat) would simply consist of one line:
R CMD BATCH your_r_script.R
otherwise, you need to give the path of R.exe, so for example:
"C:\Program Files\R\R-2.13.0\bin\R.exe" CMD BATCH your_r_script.R
you can add certain input arguments to the BATCH command, such as --no-save, --no-restore
so it would be
R CMD BATCH [options] your_r_script.R
more info on options, etc at http://stat.ethz.ch/R-manual/R-devel/library/utils/html/BATCH.html
Note: R uses the command "BATCH" to non-interactively evaluate a script located in a file. Here we are running the command "BATCH" from a windows .BAT file, but that's merely a coincidence.
An answer to another question suggests using Rscript.exe, so your batch file would contain:
"C:\Program Files\R\R-3.0.2\bin\i386\Rscript.exe" your_script.R
pause
It is a good idea to add R to the windows environment path. In a comment in this question #chase gave a link that explains how to set the path on windows 7. Once R is added to the windows path, your batch file should become simply :
Rscript.exe your_script.R
pause
You can also directly call a R command by using the -e flag. For example this batchfile will tell R to set its current working directory to Documents, then it will print the working directory:
Rscript.exe -e setwd('Documents');getwd()
pause
I struggled with the syntax with the answers below, but this worked for me in the .bat file:
C:\Windows\System32\cmd.exe /k ""path to Rscript.exe"
"path to .R script""
Be sure to place both the path to Rscript.exe and the script in "" together and separately as above.
I doubt you will be able to run it using a batch file.
http://www.fileinfo.com/extension/r
Most known programs that use .r files do so for source code files it looks like. You will probably have to compile it using the program it was written for. I guess you could use a command line compiler from a batch file, but I don't know what language or applications you are using.
If you post the script file or give more information about it, we could probably help you better.
