Question

This is my (windows) command line argument for running my script.

C:\PathToR\Rscript.exe Rfile.r input output >info.txt 2>&1

I am sending the input and output file names as arguments and then capturing errors into a text file.

How would I do this from within another R script?

Thanks.

There’s always the system() function:

return_value=system("C:\PathToR\Rscript.exe Rfile.r input output >info.txt 2>&1")

if(return_value==0)
{
  #Hooray, it worked!
}else
{
  #Boo, it didn't work!
}
