.BAT文件R脚本中的错误

Question

I have a .bat file as follows. task.bat

@echo off
R CMD BATCH C:\Users\Raghavan\Desktop\MyTask.R

The file needs to run an R script. The following is the R script.

 A<-read.csv("C:\Users\Raghavan\Desktop\A.csv")
 write.csv(A, file = "B.csv")

The R script runs by itself. However, when I try running it through the .bat file or through windows scheduler, the script fails to run. I have tried many sites.I request someoen to see if this error can be fixed. Most likely, the error is in the .bat file

Answer 1

I run my R files with the following command inside of the .bat script:

@echo Off
"C:\Program Files\R\R-3.4.2\bin\R.exe" CMD BATCH --vanilla --slave "C:\File.R"

Define the full paths to executable R and to the file that you wanna run. Hope this helps.

See also ?BATCH and this resource on arguments of R CMD BATCH.

Answer 2

I made the following edits to the code.

  @ echo off
  "C:\Program Files\R\R-3.3.2\bin\R.exe"  R CMD BATCH "D:\Newfolder\task1.R"

The files were then shifted to the D drive. This resulted in the code working.
