determinant via Lapack
Hi,
What Lapack routine(s) should I use to calculate the determinant of a
symmetric matrix of real numbers? I would appreciate any guidance on this
issue.
Thanks,
Kosuke

problems with MNP
Hi all,
Does anybody have a hint on what may be going wrong in this R code? I
mimic the sample code from the MNP developers but I seem unable to get the
choice specific variables right.
Thanks,

multinomial probit
Hello All,
I'm trying to run a multinomial probit on a dataset with 28 data
points and five levels (0,1,2,3,4) in the latent choice involving
response variable.
I downloaded the latest mnp package to run the regression. It starts
the calculation and then crashes the rpogram. I wish I could give the
error message but it literally shuts down R without a warning.
I'm using the R

R_qsort_int_I() error
Hi,
I want to use R_qsort_int_I() in my C function, but getting the
following error. It looks like there is a conflict between Rmath.h,
which I use to generate random numbers, and R_ext/Boolean.h I would
appreciate any help to fix this problem.

wrong signs using MNP.
Hi,
I recently found the MNP package. Out of curiosity, I tried to reproduce
results from Greene (Econometric Analysis, fourth edition) on page 874.
The signs of the estimates are all opposite those of Greene's table. Might
anyone be able to tell me what I am doing wrong?
I have attached the function call, the coefficients, and a few rows of the
data. The dataset has 210 observations.

RAqua and gcc
Hi,
I've recently purchased PowerBookG4 (panther) and installed RAqua 1.8.1.
I also installed gcc version 3.3 through Xcode tools. But, for some
reason, I'm having a hard time getting gcc work with R. For example, I get
the following error while installing Hmisc package. I would appreciate any
suggestion to fix this problem.
Thanks

Wish R Core had a standard format (or generic function) for "newdata" objects
Is anybody working on a way to standardize the creation of "newdata"
objects for predict methods?
When using predict, I find it difficult/tedious to create newdata data
frames when there are many variables. It is necessary to set all
variables at the mean/mode/median, and then for some variables of
interest, one has to insert values for which predictions are desired.
