R批处理文件夹中的所有文件

Question

I have a list of .R files such as UK.R , France.R , Peru.R , Australia.R , and so on, in a folder called script_countries .

Instead of doing each file separately

R CMD BATCH UK.R output.txt 

I was wondering if I could launch all the Rscripts with R CMD BATCH .

In other words, how can I R CMD BATCH all files in a directory?

Answer 1

I don't know anything about R, but a FOR loop should work:

CD "C:\adjust\path"
FOR %%G IN ("*.R") DO (R CMD BATCH %%~nxG output.txt)

If you want mutliple output files you could replace output.txt with output_%%~nG.txt or something similar.

If your files contain spaces you might want to add quotation marks around the input and output, but I don't know how R handles that.
