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 where the left hand side

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

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) library(nlme) example(nlme) # works nice ... fm1 # the fitted model ### Trying to update with different random effects

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. Michael Muller wrote: > >

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

ANOVA "ex post" Analysis
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 (happens frequently). Is a function available that extracts multiple comparison of means from objects produced by "aov()" ? Sorry if the term is not correct, I translated from german word by word ("Multiple
