plot and factors
...swer. Well, it's a
question with a couple parts. Thanks in advance for any direction
(partial or complete) that anyone can provide.
I have a data frame with three columns: Year, Semester, value1. I
want to treat Year and Semester as factors; there are many years, and
there are three semesters (Fall, Spring, Summer).
First, I would like to be able to plot the data in this frame as Year
v. value with one curve for each factor. I have been unable to do
this. Is there any built-in R functionality that makes this easy, or
do I need to build this by hand (e.g., using the techniques i...

data frames, na.omit, and sums
Dear R-helpers,
New to R, I'm in the middle of a project that I'm using to force me
learn R. I'm running into some behavior that I don't understand, and
I need some advice. In the last week I've gotten some great advice
from the list on visualizing my data, and I was hoping people could
help me get over another barrier I've encountered to my progress.

data frame to frequencies
I have a data frame that has columns Semester, Student ID (SID), Subject,
Grade, Devel (Tor F). Students can have multiple records within a semester.
Right now, the columns are not considered factors.
I want to do an analysis that would show the number of students who received
particular combinations of grades. I also need to distinguish between the

[O/T] undergrads and R
Dear R People:
Are your undergraduate students receptive to learning R, as a rule?
Most of the time, mine really like it. But this semester, they act as
though they are being eaten by rats when learning R. They are not
trying at all.
Any similar experiences? If anyone has any good ideas, I would be
THRILLED to hear them, as I am using R in Summer School.
Thanks,
Sincerely,

using R for online course/distance ed
Hi R People!
I'm going to be putting together a completely online undergrad
business stats course (a second semester course) and was going to use
R and Rcmdr.
My question: has anyone else used R for an online course, please? If
so, did it go well, please?
Thanks in advance,
Sincerely,

generate irregular series of dates
Dear colleagues, particularly academic ones,
So I'm creating a Microsoft Word template for myself so that every
time I teach a new course, I don't have to enter in the dates manually
for each class session.
I'd like to use an R script that can generate an irregular series of
dates starting from one date (semester begin) to another (semester
end) using an irregular interval in

random interactions in lme
Hi All,
I'm taking an Experimental Design course this semester, and have spent
many long hours trying to coax the professor's SAS examples into
something that will work in R (I'd prefer that the things I learn not
be tied to a license). It's been a long semester in that regard.
One thing that has really frustrated me is that lme has an extremely
counterintuitive way for

pushing out files or installs
I've got 20 windows desktop machines in a lab on a samba network. Throughout
the semester instructors usually find some software they want installed. Has
anyone come up with a good way to push out files to all these machines? I've
seen demos of software management in Windows 2003. Or any inexpensive
commercial product for software management for networks that are not Windows

[LLVMdev] Are these projects still "open"?
Hi,
I'm looking to do a semester-long course project involving LLVM.
To avoid duplicating efforts, I wanted to know if the following projects
(lifted off http://llvm.org/OpenProjects.html) are done with or are
currently worked upon. Atleast I couldn't find evidence of these in the
1.9 sources.

New Version of R?
Dear R People:
I'm not sure if I should be asking here or R-devel, but here goes:
Will there be a new version of R coming out in the next few weeks, please?
I'm setting up for the spring semester and want the students to have
the latest version.
Thanks very much,

DOE teaching suggestions?
Dear R People:
I will be teaching an undergraduate Design of Experiments class
in the Spring Semester. It will be very much an applied course.
My question, please: has anyone used R for a course like this, please?
I've tried Rcmdr for a regression course and just plain command
line for a time series course.
Should I use Rcmdr, or teach them to use the command line, OR is there

I want to use the LLVM JIT on ARM for a class project this semester.
I have built and/or installed a few different gcc arm (arm-linux, and also
one that is arm-elf) toolchains, and have had trouble getting LLVM 2.6 to
