Question

my_rscript --dataset mydataset

and then to read the optiion

Answer 1

You can call your programs using Rscript programname.r arg1 arg2 arg3. The arguments are passed to commandArgs, so the following would be true:

Rscript programname.r F N 32

> args <- commandArgs(trailingOnly=TRUE)
> args[1]
[1] F
> args[2]
[1] N
> args[3]
[1] 32
