OK. Statistics::R seens to be working fine now
I just ignores the error message in the test and went ahead with the installation, just as was told me in here: http://www.perlmonks.org/?node_id=1009156
But still I have two problems (that I hope are the last ones).
First of all, when I try to pass my table from perl to R with the comand "$R -> set( 'table', \@lines );", it returns this error:
Problem running this R command:
g1 <- table[, 3];
Got the error:
wrong number of dimmensions
I scaped that creating an output file from perl (named "data_freq.txt.out" and telling R to import from that. But this doesnt seens the right way to do it.
Second. When I try to return a table from R to perl, importing it to an array (in "my @results1 = $R->get('g1');"), I would like all the values in the table to be passed to this array (@results1). So I could shift and pop values from that array to use in other perl things (Mostly to create an nice output file)
Instead, what I get is an array with a single element that is some kind of octodecimal value (I guess)
How can I fix that?
Someone already told me to use "$results1" instead of "@results1". But that gives me the same output. Besides, it will create an scalar and that is not what I want
NOTE: "my $media = $R->get('meang1');" do work! I guess thats is because its a single value.
HERE are my codes, wich I call with "./perl-R4.pl data_freq.txt"
perl-R4.pl
#!/usr/bin/perl
use strict;
use warnings;
use Statistics::R;
my @lines;
my $line;
my $csv_check = shift @ARGV; #Mark for csv check-----
@ARGV = $csv_check;
while ( defined( $line = <> ) )
{
push @lines, $line;
}
shift @lines;
save_array_output(@lines, ".out");
print "\@lines = \n @lines ";
my $R = Statistics::R->new() ;
$R->startR ;
$R->run('library(genetics);');
$R->run('setwd("/home/user/tests/");');
#$R->set( 'table', \@lines );
$R->run('table <- read.table("/home/user/tests/data_freq.txt.out");');
$R->run('g1 <- table[, 3];');
$R->run('meang1 <- mean(g1)');
$R->run('print(meang1);');
$R->run('write.table(g1, "g1.txt");');
$R->run('write.table(meang1, "meang1.txt");');
my $media = $R->get('meang1');
my $results1 = $R->get('g1');
print "\$results1 = ", $results1, "\n";
print "\$media = ", $media, "\n";
$R->stopR() ;

be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
