Dear all,
I have searched the forums for an answer - and there is plenty of
questions along the same line - but none of the paproaches shown worked

summarystats<-as.data.frame(read.csv(file=f_summary));
where I have the columns Dataset, Class, Type, Category,..
Problem1: I want to find a subset of this frame, based on values in

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
