I haven't heard anything on this question. Is there something fundamentally
wrong with my question? Any feedback is appreciated.

Dear R gurus,
I am trying to write several large matrices (~ 1GB) to separate files. I have
learned that write.table is simply too slow for this task and was attempting to
use write.matrix, but write.matrix does not have the ability to include row
names in the output. Anyone know why that's the
Yeah, I never would have come up with that one. Thanks!

I trying to convert a list of data frames to one data frame, but one of the

Dear R Gurus,
I'm seeing some strange behavior that I can't explain. I'm generating a figure
for a paper and I like to save the script (no matter how simple) for future
reference. My practice is to write the script and run it using the 'source()'
function. What's weird is that the resultant fig

Thank you both for the tips.

Dear R gurus,
Based on my searches I think I know the answer to this question, but I'd like
to pose it to you. Is there an easy way to plot the confidence interval around
a loess line using lattice? The only thing I've found is ggplot, but I prefer
to stick with lattice out of preference.

Dear R gurus,
I'm trying to solve what I assume is a fairly simple problem, but I'm having
trouble finding the proper approach. I have a matrix where each column is some
object (e.g. a car) and each row is a numeric measurement of a feature of said
object (e.g. horse power, top speed, etc.). Le
I knew there had to be a simple solution. Thank you!

Hi,
I apologize if the solution is right in front of me, but I can't find anything
on how to convert a class of 'noquote' to 'matrix'. I've tried as.matrix and
I've tried coercing it by 'class(x)<-matrix', but of course that didn't work.
I've been using the function 'symnum' which returns an ob
That did it. Thanks!

I have a fairly simple problem, but I haven't been able to find the answer on

the font used is Arial. In my plot command I specify 'fontfamily="Arial"'. The

Dear R gurus,
I regularly come across a situation where I would like to apply a function to a
subset of data in a dataframe, but I have not found an R function to facilitate
exactly what I need. More specifically, I'd like my function to have a context
of where the data it's analyzing came from
For pete's sake! That's just embarrassing. I don't know how I missed that.
Thanks for your help Deepayan.
I would also like to say thank you for supporting Lattice so well.

Hi,
I have done a bit of searching and have not found a good answer for my
question. Although I have not difficulty ordering the panels, Lattice prints
them from bottom to top and left to right for each page. Is it possible to make
