Answer by Drew Steen is in general true, as I found this on most of the places on web. But what worked for me, I am describing below:

Steps:

1. Append "C:\Program Files\R\R-2.15.3\bin\x64" to "path" variable . This link provides procedure to set path in windows 7 os. Note that bin\x64 instead of bin, bin didn't worked for me.

2. Restart Matlab.

3. Use exec=system('Rscript.exe script.R') where the current script.R is in the current directory of matlab.

Answer 1

You can use the system function in MATLAB to execute shell commands. Since you can run R from batch files,

executed = system('R CMD BATCH path/script.R')

should work. Note that path will need to be the correct relative path to your R script from whatever your active directory in MATLAB is. executed will evaluate as 0 if the system command executed successfully (which is not the same as the R script executing successfully).
