Relative pathing via scheduled path - r

I'm trying to create a batch that can run my R script through windows Task Scheduler. I have this R project running where I can run my setup code - which applies packages and sources the rest of the script files:
C:\>"C:\Program Files (x86)\R-4.0.2\bin\Rscript.exe" "location of startupscript.r"
As soon as I get to a source command, where I have used relative pathing, with the path being
source("./Scripts/script to source 1.R")
I get an error that this file is not found, is there a way to fix this?

(Dagster) Schedule my_hourly_schedule was started from a location that can no longer be found

I'm getting the following Warning message when trying to start the dagster-daemon:
Schedule my_hourly_schedule was started from a location Scheduler that can no longer be found in the workspace, or has metadata that has changed since the schedule was started. You can turn off this schedule in the Dagit UI from the Status tab.
I'm trying to automate some pipelines with dagster and created a new project using dagster new-project Scheduler where "Scheduler" is my project.
This command, as expected, created a diretory with some hello_world files. Inside of it I put the dagster.yaml file with configuration for a PostgreDB to which I want to right the logs. The whole thing looks like this:
However, whenever I run dagster-daemon run from the directory where the workspace.yaml file is located, I get the message above. I tried runnning running the daemon from other folders, but it then complains that it can't find any workspace.yaml files.
I guess, I'm running into a "beginner mistake", but could anyone help me with this?
I appreciate any counsel.
One thing to note is that the dagster.yaml file will not do anything unless you've set your DAGSTER_HOME environment variable to point at the directory that this file lives.
That being said, I think what's going on here is that you don't have the Scheduler package installed into the python environment that you're running your dagster-daemon in.
To fix this, you can run pip install -e . in the Scheduler directory, although the README.md inside that directory has more specific instructions for working with virtualenvs.

Error that says Rscript is not recognized as an internal or external command, operable program or batch file [duplicate]

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.

How to Run an Rscript as a crontab?

I'm using a fedora system and trying to automate an Rscript on my system. So I figured out the process of getting a crontab running. However it isn't working for my Rscript.
So to test whether I can run this Rscript normally from my root (root user and ~ directory) , I'm running:
/bin/Rscript /home/computername/path_to_r_script/script.R > /root/Preprocessingv3.Rout
But this is unable to find or import libraries and hits an error at the first library being imported as:
Error in library(RForcecom) : there is no package called 'RForcecom'
Execution halted
This is strange as historically I have been running this script many times as from command line as R CMD BATCH script.R > script.Rout by cding into that path_to_r_script folder as a non root user. Unless I'm missing something very fundamental of how Linux/fedora works, there should be no reason why a script that works from one location from one user but doesn't work from a different location from root user. So I'm guessing I'm not calling it the right way.
Could any one help me understand how we are supposed to automate Rscripts (and to an extent python scripts) as crontab? And what I have to do get it running on my system?

Where is the Rserve Config file located on Windows?

I'm using a Windows 7 x64 machine with R-3.1.0. I installed the Rserve package through Rstudio.
The start of Rserve is successful with the following code in Rstudio:
library(Rserve)
Rserve()
I got the following output:
Starting Rserve...
"C:\R\R-31~1.0\library\Rserve\libs\x64\Rserve.exe"
My problem is that I couldn't locate the configuration file. Apparently it can't be "/etc/Rserv.conf".
I did come across a webpage saying that the config file is Rserv.cfg in the working directory (unless changed at compile-time). But which working directory? I have checked the working directory of the current R project as well as the Rserve library directory, but it was not there...Could someone help me with this please? Thank you.
Rserve does not automatically come with a config file, you must make one. Best steps for doing so:
Navigate to the file where you just installed Rserve.exe (C:\R\R-31~1.0\library\Rserve\libs\x64\R, based on the message you copied here)
Find Rserve.exe, Reserve_d.exe, and Rserve.dll there. Copy these files.
Navigate to where R.dll is on your computer. This is probably C:\Program Files\R\R-3.1.3\bin\x64, but may be different depending on where you installed R to.
Copy the 3 files mentioned above to this location.
Create a text file here named "Rserv.cfg" with the arguments you are looking for, such as port 6312 or library(mvoutlier). Yes, I know that this is different from the documentation, but if you start Rserve_d.exe you will see that this is the file it is looking for. I have not had success naming it anything else.
You can start Rserve by specifying the location of the config file. In R instead of just Rserve() try the following:
Rserve(args="--RS-conf C:\\folder\\Rserv.cfg")
If path is more complicated you need to massage it a little bit:
Rserve(args="--RS-conf C:\\PROGRA~1\\R\\R-215~1.2\\library\\Rserve\\Rserv.cfg")
Look in the $RHOME/bin directory
If you can't find it here is a different way to approach it:
Download Rserve at [http://rforge.net/snapshot/Rserve_.tar.gz], and save it in your desired directory
Run R CMD INSTALL Rserve_.tar.gz
This allows you to leave Rserve where you want it.
After looking at the Rserve source code and making some test I found that on Windows platform Rserve try to load the configuration file from the current working directory. Also pay attention because on Windows the file name is RServ.cfg and not Rserv.conf as documented.
The current working directory depends of the process, for example using RStudio by default it is your Documents and Settings folder:
C:\Users\[username]\Documents
but can be changed in the "Global Options" of the IDE
So you can create an "RServ.cfg" text file in that directory with your needed options and starting RServe in the usual way in RStudio
Rserve()
will load your configuration.

iexpress not executing installer

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.)
