<p>Revered Monks,</p>
<p>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.</p>
<p>Below is a minimal script. <tt>$data</tt> is created by the first 100 lines of my perl script, which I removed here.</p>
<code>
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();
</code>
<p>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.</p>
<p>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.</p>
<code>
example=read.table("file.txt", header = TRUE)
t.test(Count~Cond, data = example)
wilcox.test(Count~Cond, data = example)
</code>
<p>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.</p>
