newbie query: simple crosstabs
I've been playing around with various table tools, trying to construct a
fairly simple cross-tab. It shouldn't be hard, but for some reason it
turning out to be (for me).
If I want to see how many men and how many women agree with a agree/disagree
question (coded 1,0), I can do this:
>attach(mydata)
>mytable <- table(male, q1.bin) # gender and a binary response variable

translating sas proc mixed to lme()
Hi All
I am trying to translate a proc mixed into a lme() syntax. It seems that I was
able to do it for part of the model, but a few things are still different.
It is a 2-level bivariate model (some call it a pseudo-3-level model).
PROC MIXED DATA=psdata.bivar COVTEST METHOD = ml;
CLASS cluster_ID individual_id variable_id ;
MODEL y = Dp Dq / SOLUTION NOINT;
RANDOM Dp Dq / SUBJECT = cluster_ID

LD50 contrasts with lmer/lme4
Dear R-list,
I have a data set from 20 pigs, each of which is tested at crossed 9 doses
(logdose -4:4) and 3 skin treatment substances when exposed to a standard
polluted environment. So there are 27 patches on each pig. The response is
irritation=yes/no.
I want to determine "equally effective 50% doses" (similar to old LD50), and
to test the treatments against each other. I am looking

Fit a 3-Dimensional Line to Data Points
Hi Experts,
I am new to R, and was wondering how to do 3D linear
regression in R. In other words, I need to Fit a
3-Dimensional Line to Data Points (input).
I googled before posting this, and found that it is
possible in Matlab and other commercial packages. For
example, see the Matlab link:

Initial values of the parameters of a garch-Model
Dear all,
I'm using R 2.8.1 under Windows Vista on a dual core 2,4 GhZ with 4 GB
of RAM.
I'm trying to reproduce a result out of "Analysis of Financial Time
Series" by Ruey Tsay.
In R I'm using the fGarch library.

GLMM - Am I trying the impossible?
Dear all,
I have tried to calculate a GLMM fit with lmer (lme4) and glmmPQL
(MASS), I also used glm for comparison.
I am getting very different results from different functions, and I
suspect that the problem is with our dataset rather than the functions,
but I would appreciate help in deciding whether my suspicions are right.
If indeed we are attempting the wrong type of analysis, some

multi-class classification using rpart
Hi,
I am trying to make a multi-class classification tree by using rpart.
I used MASS package'd data: fgl to test and it works well.
However, when I used my small-sampled data as below, the program seems
to take forever. I am not sure if it is due to slowness or there is
something wrong with my codes or data manipulation.
Please be advised !
The data is described as the output from str()
