Hello all,

I am using RSPerl package to display plots in R . I want to be able to compare

some data in boxplot and in histogram and in probplot ( from e1071 package)

- ( cumulative probability plot - normal)

I have a nested arrray of data ... from perl like the following

data[0][0] = (1,2,3,.....)

data[0][1] = ( 2,1,2,2,2,2,2) - could be different lengths...

etc ( could be more two sets to compare...)

These get passed to the R engine as follows

x <- list(list(1,2,3,4),list(2,1,2,2,2,2,2))

I am trying to write a function that will perform boxplot on all this data but

I am not sure how to extract data properly and display

so far my function looks like

compareplot <- function(x,xlab=par("xlab"))

{

new.plot()

for ( i in 1:length(x))

{

# I think I have to do some assign and paste here"???

xlist[i] <- unlist(x[[i]])

args <- paste(args,xlist[i])

}

so I want my args to look something like xlist1,xlist2,....

boxplot(args)

hist(args) ...

probplot(args)

or should I do some data.frame conversion on all of the lists... and how would

I go about doing a comparison of data on probplot ( cumulative probability plot

) or histogram compare?

Thanks for any help,

Mary
