Except the list should be initialized to the final
length:
smat - vector(list, length(counts))
Growing objects is a major source of the inefficient
use of memory. If the memory grows enough it becomes
a large impact on execution time.

How about this:
hilight - function(x,y,s, bg=yellow) {
text.width - strwidth(s)
text.height - strheight(s)
rect(x,y,x+text.width,y+text.height,col=bg,border=NA)
text(x,y,s,adj=c(0,0))
}
plot(1:10,1:10,type=b)
hilight(4,4,Point)

You can investigate what's gone wrong after the loop has failed by looking
at the values of i, k, p, and t. Although d[(d[,(i+1)]%in%1),1] produces a
vector, k has only one element. Same with p. Should then be obvious why the
t.test produces an error.
The problem is with the [i] index for k and

Dear Forum members,
I have created a quasi-poisson model from a training dataset and now wish to
use the model to estimate y values for a test dataset, in order to validate
the model. The trouble is I can't figure out how to estimate y values for
the test set using the model derived from the
Hi Mike,
Thanks for the help, but I want to conduct tests, not between column 1 2
of the data but between the values of column two itself which have been
categorized into 3 classes, and indexed in column 1 as 1,2 and 3. Also if
you could help me with the commands for ANOVA for the same purpose,
I have two points of collection across 20 subjects (pre and post for each),
so 20 pairs of data points. I would like to plot the actual raw data points
for each subject for both pre and post and connect lines between these two

Des,
Please provide some information (like the results of sessionInfo) and
example code for your model. Did you use gee to fit the model and with
what function? If could be that you need to examine the type argument of
the predict function to make sure that you are getting the scale that

I'm an experimental psychologist and when I run ANOVA analysis in

are commonly used in the

It is my first time to use the R-help mailing list and doesn't have too
