very late answer, maybe the library is newer than your question, but what about optparse or getopt? `install.packages('optparse') ?optparse` [download] I tried to get it working (I come from Python and I'm used to the syntax) but in the end I settled for the easier (and working) 'getopt' solution: `install.packages('getopt') . . . if(require("getopt", quietly=TRUE)) { opt <- getopt(matrix(c('path', 'p', 1, "character"), ncol=4, byrow=TRUE)) if(!is.null(opt$path)) path <- opt$path }` [download]	[reply] [d/l] [select]
