Dear all I have two 10*10 matrixes and I would like to compare theirs contents. By the word content I mean to check visually (not with any mathematical formulation) how similar are the contents. I also know edit that prints my matrix in the scree but still one edit blocks the prompt to launch a second edit() screen. What is the best way to compare these two matrices? I would like to thank you in avdance for your help Regards Alex

I'm not sure what else you could do if you are not interested in a specific distance emasure etc. cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/

I sometimes use the enclosed sideBySide() function to
look at two printouts (of any sort of objects) in
parallel. Perhaps that would help.
sideBySide <- function (a, b, argNames)
{
oldWidth <- options(width = getOption("width")/2 - 4)
on.exit(options(oldWidth))
if (missing(argNames)) {
argNames <- c(deparse(substitute(a))[1],
deparse(substitute(b))[1])
}
pa <- capture.output(print(a))
pb <- capture.output(print(b))
nlines <- max(length(pa), length(pb))
length(pa) <- nlines
length(pb) <- nlines
pb[is.na(pb)] <- ""
pa[is.na(pa)] <- ""
retval <- cbind(pa, pb, deparse.level = 0)
dimnames(retval) <- list(rep("", nrow(retval)), argNames)
noquote(retval)
}
Try:
> x1 <- matrix(sort(rnorm(100)),10,10)
> x2 <- matrix(sort(rnorm(100)),10,10)
> sideBySide(x1,x2)
