I am creating an R script myscript.R which manipulates an excel file by means of XLConnectpackage.
The point is it refers to several external files: the excel file itself and another R file (functions library), so I need to set a working directory in the location of the script (so that relative paths to external files work properly).
I am using the following in my script
new_wd <- dirname(sys.frame(1)$ofile)
setwd(new_wd)
When I source the script from my RStudio it gets the job done. The problem is that the script is to be used by non-programmers, non-Rstutio-users, so I create .bat file (which I want to turn into an .exe one)
"C:\Program Files\R\R-4.0.3\bin\Rscript.exe" "C:\my\path\to\myscript.R"
It executes the script line by line but sys.frame(1) only works when sourcing.
How could I solve it?
Thanx
I have found a solution and it works properly.
From CMD command line or from a .bat file one can add an argument -e to the command, so that you can use a R language.
absolute\path\to\Rscript.exe -e "source('"relative\path\to\myscript.R"')"
It worked for me.
Besides, as Compo commented, I think there's no need for a .exe file, since a .bat does the job.
I have successfully run a simple cronR tutorial using the cronR add in within R Studio. Here is the following code that I have saved in a R script file:
library(glue)
current_time <- Sys.time()
print(current_time)
msg <- glue::glue("This is a test I am running at {current_time}.")
cat(msg, file = "test.txt")
The R script file is saved within a specific project directory. The log file when the job runs is also saved there. However, the output of the script file, test.txt, is saved in my home directory. I am on a Mac. In the tutorial, it was stated that this would happen, that cron would save any output in the home directory and that if I want to change the location that I have to "specify otherwise". However, the tutorial gives no instructions for how to do this and I am not sure if I am supposed to do this through the terminal in mac and if so how? Changing the file path in the script file (e.g. Documents/test.txt) changes nothing, as the test.txt file is still saved in the home drive. I suspect I have to make this change somewhere else but I am not sure where. Any help would be appreciated.
For anyone who runs into the same issue, I was able to solve my problem by using launchD. I followed this tutorial https://babichmorrowc.github.io/post/launchd-jobs/. It worked as anticipated and now my .txt file is saved to the correct place. There is also a tutorial there for cron jobs, though if you are on a mac, launchD is apparently the preferred method.
I would like to use the directory of my bat file to run my R script.
My R script is in the same directory as my bat file, I tried:
"C:\Program Files\R\R-3.1.2\bin\x64\RScript.exe"
"%CD%\script_to_run.R"
but the cmd immediately closes.
This works if I specify the entire path of my script instead of using %CD%.
Can I have some help, please?
The simplest fix is to use:
"C:\Program Files\R\R-3.1.2\bin\x64\RScript.exe" "%~dp0script_to_run.R"
Where %0 references the running batch script and %~dp0 references the drive and path of the running batch script, (ending with a trailing back slash).
To start, or run a program in a batch script, you have to right start at the beginning. It would look like this,
start yourfilepath
I hope this helps, if not, tell me and I will try to help.
I want to upload an image file using an AutoIt script:
WinWaitActive("Open")
Send("D:\sprint8execution\gGastro-mvn\tmp.png")
Send("{ENTER}")
How to give the system-defined path in the script so that if the script runs on any other machine it goes to applicable directory and fetches the image from there?
Have a look to the AutoIt macros. #ScriptDir is the directory that includes the current running script.
I am working with PyCharm 4.04. Since I installed it, every time I open it, as default directory I get this:
C:\Users\Laura\AppData\Local\Temp\main.py1.tmp>cd
Which gives me an error when trying to use the console:
Error:Cannot start process, the path specified for working directory
is not a directory
But even if I change the directory, the message does not disappear.
The terminal, though, it does work and I can run projects, but I would like to use the console.
Another solution is to close the project, run rm -rf .idea and re-open it. Apparently Pycharm gets confused by some direct folder manipulation and doesn't reflect it properly in his .idea/*.xml files
I also got this error, and it got resolved by setting the default working directory. Follow the below path, and set the Working Directory to the folder where your code resides.
File > Settings > Build, Execution, Deployment > Console > Python Console > Working Directory ...
I finally solved the problem.
I think it all started because the first project that I opened with pycharm was in my "download" folder, so the working directory was automatically set to a temporal folder by default and allthough I moved the project to another folder and I manually changed the working directory from the terminal, it was not working.
The solution was creating a new project and giving a correct path to the new project. It seems very easy but it was not that obvious.
In the upper right corner click on small ▼ next to your main to run (look to the left from green right-pointing triangle)
Select Edit configurations.
In ▼ Python select the proper configuration name.
Look at the Configuration panel.
Fix items Script and Working directory.
pycharm
I had this same problem and just had to reinstall pycharm. It's a quickfix and I can't ensure it won't happen again.
I solved this by replacing all instances of the old filename and old directory with the new one in .idea/workspace.xml
It can be done with PyCharm running.
#user1068430 has the answer in the comments to the question:
When you open a project open the directory not a specific python file.
Instead of ~/Documents/myProject/main.py open ~/Documents/myProject
If you "open" the .py file then you'll have to set the working directory (File > Settings > Build, Execution, Deployment > Console > Python Console > Working Directory) every time. If you "open" the directory containing the .py file, then PyCharm will open and all of your .py files will be available in the left window. Select one of them and you're good to go.
i had the same issue, the error comes up when i want to upgrade my packages and when i run my project "this FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\youruser\AppData\Local\Temp\gen_py\3.7\__init__.py'" i found that the Temp file in C:\Users\youruser\AppData\Local was corrupt and it was fixed by deleting the "Temp" file, once deleted it will automatically create a new one with "gen_py" in it
To anyone with similar issues: Python interpreter virtual environment is where your python.exe sits. The working directory is where your script sits. To make everything easier, open a new project, scroll to location where you script is stored, and select. Click the interpreter option, click existing (if old one worked) or choose the python.exe. When asked, open the project in a new window, close old one to avoid confusion.
source = banging my head against the console for past few hours.
if the above mentioned solutions are not working, you can restart a new project.
file > New project...
then,
create a new project.
