Hi Jim,
that's exactly what I'm looking for. Thank you so much. I think, I
should look for some further documentation on list handling.
I think I will do the same...
Thanks to Jim I learned textConnection and rowMeans.
Jim, could you please go a step further and tell me how to

the same for v5, v6 and v7
further, I'm not sure how to avoid the list, because this is the
result of the processing I did before...
Ciao,

I have the following two problems, related to the function sub, grep,

Dear R-Users,
I'm currently studying the book
Statistical model in S by Chambers J.M and Hastie T.J..
At page n 3 there's a plot showing the means of a variable at each of the
levels of the factors of an experiment.
I hope to be able to reproduce it here by ASCII art.

Hi all,
I would like to add to each panel of a bwplot a coloured central band,
centered on the mean of the values, being its width +- 2% of the mean
itself.
I know how to add lines, i.e. something like
bwplot(X ~ Y|FACTOR
data=my.df,
panel= function(x, y){
panel.bwplot(x,

I have a panel data set (25 years) and I would like to break
it up by year, and run a few tests. How is this done in R?
In STATA it is quite simple (keep if year =1970). If someone

Hi all,
first of all thanks for the answer to my previous question on lattice some
time ago.
In particular to Patrick Connolly for advices on netiquette (I hope this
time I'm doing right)
and to Deepayan Sarkar fro the help on lattice.
Now, my nowaday problem.
Please consider the following
Dear R users,
this is my first question to the list.
I hope it will be not a trivial one.
My problem is to change the order in which the panel are plotted in a
lattice/Trellis plot.
I've read the S-plus Trellis Graphics user manual, in which there is a
function called reorder.factor,
that, as far
