Hi,
Hadley recently proposed a strategy using plyr for a very similar problem,

Also this looks like homework, so I can not really reply with a

I've found the functions in the psych package easier to use than the

Hi,
I've got a linear mixed model created using lmer:
A6mlm <- lmer(Score ~ division + (1|school), data=Age6m)
(To those of you to whom this model looks familiar, thanks for your patience
with this & my other questions.) Anyway, I was trying this to look at the
significance of my fixed effects
Detach the coda library. Its HPDinterval is conflicting with the
HPDinterval in lme4. You should have gotten a warning message about
the conflict when you tried to load coda.

Hello!
I have this problem: I want to create a Venn's diagram with three lists of
genes'names. The first is all the genome, the second a subset of it comprising
all mitochondrial genes, and the third including all genes that correlate with
a given gene.
This is what I do:

Gabriele,
Take a look at this:

Hi,
When using splom() in the lattice package, I would like to be able to
access the row and column number of each individual pairs plot ,
similar to the way that current.row() and current.column() can be used
in other lattice plotting functions such as xyplot. For example, I
would like

See ?reorder. Typical usage would be (in lattice)

You should read the r-help list more often. Gabor Grothendieck gave an
example of the use of xtabs() this very morning.

Hi:
You could complete the entire process in one shot with the plyr package,
using
function ddply. Using the piece of data supplied,

I'm an R newbie and had the following question. I'm trying to run a logit model
because I have a dependant variable that is a factor with three levels. Each of
my independent variables are factor variables and have two or more levels,
which is why I'm unsure about the error.

Could anybody please help me with this? In the following function, I try to

I tried format(x, trim = TRUE), but didn't work.
If my x has only first three components, which are all integers, I don't run
