Re: [R] How two compare two matrixes
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)

I don't see why you would want to do this, but you could always invoke two instances of R and create one matrix in one and the other in the second. Peter Ehlers This is that makes comparisons not that easy to the eye. From the other hand with edit(mymatrix) I get scrolls so I can scroll to one row and see only the area I want to focus in. Problem with edit is that it blocks cli and thus I can not have two edits running at the same time.

Maybe you could write both matrices to files and compare them in an external viewer (Excel, less, ...). If I remember correctly, the object browser/data viewer of JGR allows editing several objects at once. cu Philipp -- Dr. Philipp Pagel Lehrstuhl für Genomorientierte Bioinformatik Technische Universität München Wissenschaftszentrum Weihenstephan Maximus-von-Imhof-Forum 3 85354 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

That's the problem Even a 10*10 matrix does not fit to the screen (10 columns do not fit in one screen's row) and thus I do not get a well aligned matrix printed.
