tm[,-1]
This does what I was hoping it would:
aggregate(tm[,-1],by=list(tm[,10]),FUN="mean")
but I don't know what "tm[,-1]" means (well - the -1 bit anyway.
Does it somehow means the whole matrix?
Please don't tell me to check the manual - I tried and failed dismally...

two questions for R beginners
* What were your biggest misconceptions or
stumbling blocks to getting up and running
with R?
* What documents helped you the most in this
initial phase?
I especially want to hear from people who are
lazy and impatient.
Feel free to write to me off-list. Definitely
write off-list if you are just confirming what
has been said on-list.

Help useRs to use R's own Time/Date objects more efficiently

I wanted to modify my first suggestion.
Perhaps a better idea would be to reference an external document
giving an overview of the subject.

removing of memory - optim()?
Dear all,
I have the following problem: I am using Windows XP as OS and have a R
program which uses optim() in a loop. Although I overwrite every variable in
the loop the memory R is using is increasing until my system breaks down
because the swap file is getting just to big. I suspect that optim() is
creating some variables which are not deleted automatically. So I tried to
do the following:

Using R in a university course: dealing with proposal comments

I am scheduled to teach a graduate course on research methods in

Docs: Re-organizing the LLVM docs
As part of my Google Season of Docs project, I’ve been conducting a content
audit of the LLVM docs. My goal is to identify specific categories and
tasks under which the docs can be re-organized. One of my first suggestions
will be to turn the main index (llvm.org/docs) into a landing page of
sorts. Here’s an example of how the new index page might look:

$
If object is user defined is:
object$df.residual
the same thing as
df.residual(object)
This is my first time to encounter the $ sign in R, I'm new. I'm
reviewing "summary.glm" and in most cases it looks as though the $ is
used to extract some characteristic/property of the object, but I'm not
positive.
Thanks
