Passing multiple arguments via command line in R

Question

I am trying to pass multiple file path arguments via command line to an Rscript which can then be processed using an arguments parser. Ultimately I would want something like

Answer 1

In the front of your script test.R, you put this :

args <- commandArgs(trailingOnly = TRUE)

hh <- paste(unlist(args),collapse=' ')
listoptions <- unlist(strsplit(hh,'--'))[-1]
options.args <- sapply(listoptions,function(x){
         unlist(strsplit(x, ' '))[-1]
        })
options.names <- sapply(listoptions,function(x){
  option <-  unlist(strsplit(x, ' '))[1]
})
names(options.args) <- unlist(options.names)
print(options.args)

to get :

$inputfiles
[1] "fileA.txt" "fileB.txt" "fileC.txt"

$printvar
[1] "yes"

$size
[1] "10"

$anotheroption
[1] "helloworld"
