Hi all,
I want to run a R code in the batch mode under UNIX system.
Inside that code, I have a usage() function to give the hints regarding
parameters. For example
usage = function()
{
msg = "R CMD BATCH --save \"--args path=\\\"input_path\\\"
file=\\\"input_file\\\" [seed=\\\"integer\\\" proportion=\\\"[0-1]\\\"
outpath=\\\"output_path\\\" outfile=\\\"output_file\\\"]\"
/S/hxd/utils/sampleRecords.r.txt";
print(msg);
}
When I run the code like
R CMD BATCH mycode.R, I want to output the usage info if the required
parameters are not there. But how to output the usage info listed above to
standard out rather than to a file?
Thanks.
HXD
