[Bioperl-l] data into R from Perl arrays

Hi,

a very simple doubt, but I do not know how to manage this.

I want to plot a histogram for all data in 'datos.txt'.

a) by using R:
datos<-scan("datos.txt")
pdf("xh.pdf")
hist(datos)
dev.off()


b) How could I invoke R inside Perl to do the same??
#!/usr/bin/perl
open(DAT,"datos.txt");
while (<DAT>) {
 chomp;
 push(@datos,$_);
}
#now I want a histogram of values in @datos

Thanks!!

JR
