R help - Mar 2008 - Nothing happened when I using t.test throuth RSPerl

Hi,   

I've just started using RSPerl. Though also tests in directory
"/usr/local/lib/R/library/RSPerl/tests/" are passed successfully, I
meet the problem with the following codes;

use strict;
use warnings;
use R;
use RReferences;

my @array1=1..10;
my @array2=1..39;
&R::initR("--silent");
&R::library("RSPerl");
my $tt=&R::call("t.test", (\@array1, \@array2))
print $tt;


I got the messages:
Can't locate package RFunctionReference for @RReferences::ISA at testR.pl
line 4.
Use of uninitialized value in print at testR.pl line 11.

Thanks in advance

That is a *Perl* error, and my guess is that you haven't set your 
environment variables correctly.  R was not even started.

RSPerl is an Omegahat package, and as the Omegahat mailing lists were down 
(last time I looked) I suggest you contact the author.  The R posting 
guide asks that non-R programming questions are not sent here (to R-devel, 
if an R list is appropriate).
