Problems executing script from command line in R. Error message: cannot find path specified

Question

I have been trying to execute a simple test.R

setwd("C:\Users\jdd\Documents")
test <- 2*6598
filename = "test.csv"
write.csv(test,file=filename)

Via the following command line command in Windows:

"C:\Program Files\R\R-2.15.2\bin\R.exe" CMD BATCH   --vanilla --slave "C:\Users\jdd\Documents\test.R"

When I execute this I get the following error:

The system cannot find the path specified.

I have been trying to work out a solution on the basis of the provided error message, but failed so far. Wondering if somebody can help me so I can execute the script directly from the command line. Thanks

Answer 1

Thanks @sebastian-c! I tried to use RScript, which I investigated before. However, the problem was a different one. Appears that in my installation there is a R.exe and Rscript.exe file in .\bin, but also one in .\bin\x64. The first one is not working properly, but the second one is. The comment made by @Roland is very important as well, since once working I got this error message!

The following command did the job:

"C:\Program Files\R\R-2.15.2\bin\x64\Rscript.exe" "C:\Users\jdd\Documents\test.R"

and the corrected text.R is:

setwd("C:\\Users\\jdd\\Documents")
test <- 2*6598
filename = "test.csv"
write.csv(test,file=filename)

Answer 2

As mentioned here, it might has something to do with 64bit version of R. The problem is that Rscript.exe itself is attempting to access a missing file on the system. The obvious fix is explicitly add 'x64' to the path of the other Rscript.exe that was installed:

"C:\Program Files\R\R-2.15.2\bin\x64\Rscript.exe" --version
R scripting front-end version 3.0.2 (2013-09-25)
