Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:
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.
