Hello,
I have recently started to use moodle (a course management system) for
my classes. It has turn out to be a very interesting tool. I woke up
this morning wondering about the possibility of adding a module so that
the students could use R without needing to install it, just using a
server
Dear Deepayan,
The application in which I encountered the problem is much more complicated,
so I'm not sure whether using groups will work there, but I'll give it a
try.
Thanks for this,
John

Many thanks: R CMD SHLIB is proably what I was looking fordo you know
where the most extensive documentation for that is located? I looked at
the man page for R and R CMD SHLIP --help, but there wasn't much detail on
how it works. Does it (or can it be configured to) run a
Hi Everyone,
I posted a similar question about a week ago, but haven't gotten any
replies -- I'm afraid that's because my previous question was too
vague. Let me try again with a more specific question, and I hope
someone can help. NOTE, I know I should be using the newer lme4
package, I
Hi,
I would like to compare several Generalized Linear Models on the basis of BIC.
My models have a binary response variable and are fitted with the glm function.
AIC works well, not so BIC
I tried:
testBIC-glm(y~x1+x2+x3,binomial)
BIC(testBIC)

I was wondering, if it is possible to print out the
values of variables while you are in a for/while loop?
Like this for example:
for (i in 1:5) {
i
}
yes, should be

Dear List,
I am new to R. I would like to compute the permutational exact p-value for the
Kolmogorov-Smirnov test for paired data. Is there a routine that is available to
do this? Thanks.
John

I found a very odd thing.
A matrix multiplied by its inverse matrix should be an
identity matrix.
But why the following thing happens?
a%*%solve(a) is not an identity matrix

Well, an invertible matrix multiplied by its inverse...
The matrix that you give (to two decimal places) is singular

I have not had a great amount of success installing/updating packages

installing from loacal zip files.)
But I am not asking for help in using these facilities because I prefer
to keep a folder of package zip files. On the other hand

Quite right. Thanks for catching that. Recurrent trouble with
non-reproducible examples...

Have you received a reply to this post? I haven't seen one. I agree
that VarCorr(lmer(...)) is unhandy if I want to do further
computations with those numbers, which I often do. The following solves
that problem, at least for the example in the lmer VarCorr documentation:

Dear Group,
I have a matrix (157 X 157 ) with correlation values.
I want to convert the unique elements into a long list
so that I can add an extra variable and plot them.
Example:
A B C D
alfa 1 0.3 0.8 -0.3
beta 0.2 1 -0.3 0.4
echo 0.9 -0.3 1 0.5
tang -0.5 0.5
See ?reshape
