Problem with multiple factors in nlme
Dear R-experts,
I have a problem to formulate non linear mixed effects when more than one
explanatory variable is present. I'm using R 1.1.1 under Linux. The
version number of the nlme library is 3.1-7.
"help(nlme)" says that among several possibilities it is possible to code
fixed effects according to
fixed = a1 + a2 + ... + an ~ X1 + X2 + ... + Xm

Problems with "help(topic,offline=T)"
Hello everybody,
since I installed R-0.90.0 (Linux 2.0.25) I have problems with generating
printable output with 'help()'.
Default output to the terminal ('echo $PAGER' gives 'less') works o.k..
When invoking 'help(topic,offline=T)' all the usual procedures seem to
start: 'top' reports invocation of latex as well as of dvips. But after
finishing there is

(Fwd) Re: 3d in R
In Win95/NT you can use xgobi (program and R interface) as well,
provided you will install an x-server on your machine (a free one is
available from http://www.microimages.com/freestuf/mix/).

Strange behaviour using .Fortran
Hello everybody,
I observed some strange behaviour of R (0.64.1/Linux 2.0.25) when trying
to use FORTRAN-libraries.
I first downloaded "ALGORITHM AS 304" from StatLib. All I changed at
the code, was to substitute "REAL"-routines by "DOUBLE PRECISION".
Compiling went o.k.:
> g77 -fpic -O2 -shared -o rtest.o fisher.f
("g77 --version" gives 2.7.2.1)

fromulation of random effects (nlme)
Dear all,
I have a problem formulating random effects when using the nlme package.
?nlme says that the random effects can be a formula or a list of formulae.
But when trying to do so, I run into trouble.
(R-1.2.2, nlme-3.1-10, Linux)

MANOVA / Hotelling's Test
Hi everybody ...
I have to perform Hotteling's T^2 Test - more generally a MANOVA - on a
set of data. Is there a (simple?) possibility to do it in R?
The somewhat obvious way to do it would be
> summary(aov(Y ~ x1 + x2 ... + xn))
where Y would be a two-column matrix.
But this does not work in any possible combination of matrix or factor
dimensions! Is it principally not possible

R-1.9.0: configure/install problem
Dear R-helpers,
for the first time since R-0.6x I have to face installation problem. I
switched to a new Linux-box (SuSE 9.0) and installed as many libraries as
possible.
R-1.9.0.tgz went to /usr/local/lib and was extracted without problems.
After running properly for a while, 'configure' (called without any
switches) gave
"configure: creating ./config.status" which was

So it looks like the verifier doesn't catch this condition - I think it
should. The attached program reproduces the problem - verification succeeds,
but the linker fails with a type assertion.
BTW, if no one has the bandwidth to work on this I'm willing to attempt a fix,
assuming that you agree that the verifier should discover this condition.

Y-limits of barplots
Hello everybody,
I frequently have to produce barplots from variables the natural variation
of which is far away from zero. A typical range would be, say from -16 to
-28.
So, the following example should give an "honest" presentation:
x<-c(-20,-22,-21,-28)
barplot(x,beside=T,ylim=c(-18,-30))
But using anything else but "0" for the first element of ylim
leads to strange

Compilation error of R-2.14.0 on Mac OS 10.7.2
Dear R gurus,
I attempt to install the latest version of R from source on my MacBook Pro, using latest versions of Xcode and gfortran for Lion and configure options:
./configure --with-libintl-prefix=/sw --enable-R-shlib (this last option necessary to further install the Rpy Python package)
I got the following unreduced compilation error:

Hello everybody,
shame on me if I have overlooked something (CRAN, StatLib), but I think
I've searched carefully. Maybe it's just too obvious to see for me

objects produced by "aov()" ? Sorry if the term is not correct, I
