From: R A F
Subject: commandArgs()
Apologies for asking about this, but I don't quite understand how
this works after looking through the FAQ and the Help archives.
Let's say I want to pass "1000" as an argument to R. I did the
following:
>R CMD BATCH --1000 infile outfile
When I do print( commandArgs() ), I see
[1] ".../R.bin" "--restore"
[3] "--save" "--no-readline"
[5] "gui=none" "--1000"
So commandArgs()[6] is the argument I want. Does one then go on and
remove the "--" manually and cast this as numeric? If so, what's the
usual way to do this? Or am I not understanding this mechanism
properly?
Thanks very much.
