Feed data to R using Statistics::R

[Anonymous Monk]

Revered Monks,

I am trying to use Statistics::R to run a simple t-test, but I am having a hard time feeding the data to R from my perl script.

Below is a minimal script. $data is created by the first 100 lines of my perl script, which I removed here.

use strict;
use warnings;
use Statistics::R;

my $data = 
"Subj    Cond    Count
subj1    high    13
subj1    low     15
subj2    high    12
subj2    low     15
subj3    high    16
subj3    low     17
subj4    high    11
subj4    low     18
";

my $R = Statistics::R->new();
$R->startR;
#$R->send(qq`data = scan()\n$data\n\n`);

#my $r_output = $R->read;
#print $r_output . "\n";

$R->stopR();

Using "scan" does not work. The example in the documentation is too simple, it only contains one number. Also, I do not understand what the qq, q and backticks are in the argument of "send" in the documentation.

Normally in R I would run the following commands, but I would like to avoid writing the data out to a file and reading it back in.

example=read.table("file.txt", header = TRUE)
t.test(Count~Cond, data = example)
wilcox.test(Count~Cond, data = example)

If per chance someone uses the package, I would be grateful for any help. I am an R beginner so there may be ways of reading in data I do not know about.
