I want to run my R code through Jython. I have not used Jython before. Can anyone of you please tell me how can I do? Can rJython help me to do so?

I deal with a problem in R Studio. When I choose to save my work, this message shows up
And if I try to close the program, this message shows up
Any ideas why this happens? Also, I would like to ask if it is better to use the latest version of R (R4.0.2)?
Thank you for your answers. The problem was that I had open an R script file which I had deleted before. When I remove this script, Rstudio works fine.
I have written a series of R Scripts that create csv files. From there, Tableau will read the csv's and update various dashboards. As Tableau can easily be scheduled to update on a daily cadence, I was hoping to do the same with my R Script.
While there are a bunch of answers already with solutions for Windows, there hasn't been a solution posted for OSX. I have looked into trying to run my script in Terminal and use automator to do it, but couldn't quite figure it out. Basically, when the shell script runs it terminates midway through because there are errors in the R Script - but I do not care about the errors. The Automator didn't work as well.
Additionally, I also looked into Data Integration/Pentaho but the additional software configuration and subsequent installation seemed difficult.
Any help or insight would be greatly appreciated! Thanks!
Type crontab -e and add this line to the resulting file
#daily Rscript 1.R && Rscript 2.R
It will run the files 1.R, followed by 2.R at midnight every day. Hope that helps.
The most flexible way to do this is to use launchd, the service that manages processes on OS X. You can look at some examples in the official documentation.
Is it possible to Execute a .bat file within the R console? I know I can run R in batch mode, but am wondering if I can start a .bat file from the R code within itself. I have googled it and cannot seem to find an answer. Thanks in advance!
I guess you could use system command for invoking OS commands. Please check here for more info.
First off, I'm unfortunately a windows user. So downloading Rtools and being able to use it from the command prompt is a bit of a pain. However, I figured it out. And everything worked fine. Just recently, however, I have not been able to run R from the command prompt using the R command. This did work at one point. However, now when I execute the command R in the command prompt R opens but when I type some R code (q(), matrix(1:4,2,2), etc...) and hit enter nothing happens. This is very bizarre. Has anyone else experienced this? Does anyone know what is wrong?
One last thing. I have tested the following R CMDs, INSTALL, SHLIB, build, check. They all work fine.
Thanks in advance!
I've downloaded and installed Rconn as well as Rexcel. The API appears to be working as I am able to copy my code from R into Excel and then, through the use of the API GUI I am able to extract values for one of my matrices.
The problem I'm having is within VBA. When I try and run the following line:
RInterface.StartRServer
I get the following error message: "Run-time error'424': Object required"
Would anyone be able to help me understand why I'm getting this error? Am I perhaps meant to load something from "Tools/References"?
Any help would be greatly appreciated
Thanks
Mike
I managed to sort it out. It was a reference problem. Once the rconn and RExcel are install you have to go to tools>References>RExcelVBAlib.
This will then allow you to use RExcel within VBA
