Dear monks,
Forgive me in advance here but I need a little help in R. Does anybody know how to pass parameters to an R script and use them within the script? If I were to do this in Perl it would go like so:
#!/usr/bin/perl -w
use strict;
use Data::Dumper;
my $x = shift;
# ... then i can play with $x here
my @xvalues = (1 .. $x);
my @yvalues = map { $_ ** 2 } @xvalues;
print Dumper \@xvalues, \@yvalues;
exit (0);
So how can I do this in R? The documentation says to use
args <- commandArgs(TRUE) but does not really say more than that. What I've got so far is something like this:
#args <- commandArgs(TRUE)
# This works okay but I would like to replace 10 as a parameter though
x <- c(1:10)
y <- c(x^2)
png(filename="plot.png", bg="transparent")
plot(x, y)
dev.off()
Any help is much appreciated =)
