incorrect behaviour of formals (PR#4511)
Full_Name: Jörg Polzehl
Version: 1.8.0
OS: Windows XP
Submission from: (NULL) (62.141.176.1)
I encountered a problem when playing with the mle library and specifying
negative
starting values for the parameters.
The reason seems to be an incorrect behaviour of function formals:
glike<-function(a=1,b=1,c=1) a
> formals(glike)
$a
[1] 1
$b
[1] 1
$c

Problems with R CMD INSTALL on SUSE-LINUX 9.0
Dear Colleagues,
I've recently upgraded to SUSE-LINUX 9.0 and R 1.8.1 (using the
RPM-'s from CRAN).
I've checked that all required LINUX-Packages as listet in the
README.html in /bin/linux/SUSE
are installed.
I've then tried to INSTALL and check a package.

Problems Compiling sshd - OpenSSH 3.8p1 on Tru64 UNIX V4.0F PK#7 (OSF)
I am trying to compile sshd 3.8p1 on Tru64 UNIX V4.0F Patch Level 7.
Previously I've compiled the entire 3.6.1p2 distribution with no problems.
The problem seems to occur when linking sshd. The linker is unable to find
xcrypt and shadow_pw functions (openbsd-compat/*.c). The libopenbsd-compat
seems to have built without errors. I configure as follows:

R for Computational Neuroscience?
Hi all,
I've noticed that many computational neuroscience research groups use
MATLAB. While it's possible that MATLAB may have some features
unavailable in R, I suspect that this may instead simply be a case of
costly tradition, where researchers were taught MATLAB as students and
pay for it as researchers because it's all they know.
I'd like to attempt to break the cycle by

density estimation in two dimensions
Hello,
I am a newbie to R and the subject of density estimation in two
dimensions or more.
I would like to have some advice concerning a comparison between the R
packages
for density estimation in bivariate or higher order problems; I mean
explicitly
the packages:
1) ash
2) KernSmooth
3) locfit
4) sm.

Error in outer() : dimension mismatch
Dear R users,
I am a new R user and have some difficulty
understanding the functioning of “outer”, where my question is from. I have
read the posts related to the questions on the outer function, but
unfortunately could not figure out where my mistake is.
I have a function with two variables and
three parameters (a density function that is not standard) and I want to draw

How the change the dimension of an individual cell [i.e. the cell corresponding to an observation in data matrix] in a heatmap.2?
Dear R-Helpers,
I have a short question related to heatmap.2 function. I wanted to change
the dimension of each cell in the heatmap drawn by this function.

x <- as.matrix(mtcars)

help with bivariate density plot question
Dear R users:
I have a dataset with two variables (>20000 observations, two samples from same subject) and I used "kernSur" from library(Genkern) to
get a estimated bivariate density and corresponding plots as follows:
new.data.normal<-data.normal[!is.na(data.normal[,2]),]
x<-new.data.normal[,2]
y<-new.data.normal[,3]

Kernel density / weights matrix?
Dear everyone,
I'm coding the Horowitz-Spokoiny (2001) test [1], and I would be very
grateful or some advice regarding the Kernel density (apologies
beforehand if my terminology is not fully correct). I have looked into
ksmooth and npreg, but with no success.
Given a (n x p) matrix of covariates X, I need to construct the
following matrix of Kernel densities or weights:

Lapack, determinant, multivariate normal density, solution to linear system, C language
r-devel list,
I have recently written an R package that solves a linear least squares
problem, and computes the multivariate normal density function. The bulk
of the code is written in C, with interfacing code to the BLAS and
Lapack libraries. The motivation here is speed. I ran into a problem
computing the determinant of a symmetric matrix in packed storage.
Apparently, there are no explicit

Random intercept model with time-dependent covariates, results different from SAS
Dear list-members
I am new to R and a statistics beginner. I really like the ease with which I can
extract and manipulate data in R, and would like to use it primarily. I've
been learning by checking analyses that have already been run in SAS.

mosaic plot of "vcd" package does not stretch with 2-dimension?
Hi,
I like mosaic function of "vcd" package. I have played around it. I
have found out that mosaic plot data table is 2-dimension does not
stretch when you enlarge a mosaic plot. It is okay when data table is
3 or more dimension. The first one is of 3-dimension table case, and
the second one is 2-dimension. With the first plot, you can drag
window to enlarge a plot. With the
