summing array elements
Hi to everybody I have an array with dimensions 2,4,3,3. Wanting to sum the matrices in the first two dimensions, I'm trying to use the "apply" function, but with no results. Have to say I'm quite new with R syntax. tx in advance marco [[alternative HTML version deleted]]

Change page in postscript()
Hi, Another question about graphics... Suppose I have: par(mfrow = c(4, 6)) which will set up a figure region for 24 plots. But, I actually only need 23 plots. In fact I wrote a little function, foo.plot, which will draw all the 23 plots at once with: foo.plot(x) where x is a data frame. Now, suppose I want to draw several set of these 23 plots, but want to put them all in one postscript

median of binned values
Dear list, I have a vector (array, table row, whatever is best) of frequency values for categories (or bins), and I need to find the median category. Trivial to do by hand, but I was wondering if there is a means to do it in R in an elegant way. The obvious medioan(vector) returns the median frequency for the binns, and that is not what I want. i.e,: freq cat1 1 cat2 10
