Hello everyone! I am a student and I am learning Perl. For my project I am writing a script whose output is a .csv file and I would like to call an R script from the Perl script so I could show the results from my .csv in a graph. I have a code which works in R:

setwd("C://PerlProject")
# loading data into R
indata <- read.table ("result.csv", colClasses=c(NA,"NULL","NULL",NA,N
+A,NA,NA,NA,NA), header = TRUE, sep = ",")

# load the stats package
library(stats)
mydata <- indata[,2:8]
ir_pca <- prcomp(mydata,
                 center = TRUE,
                 scale. = TRUE)

scrs <-ir_pca$x[, 1:2]
pdf("plots.pdf", width=16, height=16)
plot(scrs)
text( scrs, rownames( indata ), pos= 3 )
dev.off()

but I am having real troubles integrating it in my Perl script. I've instaled the Statistics::R package, but when I tried to put these commands in the $R <- run () way, I just get a bunch of errors. Could anyone at least give me some tips how to go around it? Thank you so much! p.s. The file 'result.csv' is a variable $result in Perl, I am not sure how to connect these too?
