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

error bars on barplots
Hello again
I'm trying to put error bars onto a barplot. I've tried something that
Bill Simpson suggested a while ago, ie:
x<-c(1,2,3,4,5)
y<-c(1.1, 2.3, 3.0, 3.9, 5.1)
ucl<-c(1.3, 2.4, 3.5, 4.1, 5.3)
lcl<-c(.9, 1.8, 2.7, 3.8, 5.0)
plot(x,y, ylim=range(c(lcl,ucl)))
arrows(x,ucl,x,lcl,length=.05,angle=90,code=3)
#or
segments(x,ucl,x,lcl)
but I can't get it to work on a

command history under cursor keys
g'day R friends,
I was hoping someone could provide me with advice as to my dysfunctional
'arrow' keys.
Instead of browsing thru my command history they just move my cursor. What
have I done wrong? My TERM seems ok for other unix apps.
I'm running under hpux 10.20 with R1.0.0
thanks,
John Strumila

Does anyone know of any SOM library for R? or any stand alone freeware?
A search from google returns SOM_PAK 3.1 developed at Helsinki University

GLM available book recommendation
Howdy,
I looked at the references in the R and S-Plus literature to find a
good introduction/reference to GLM. When I then went to Amazon it
seemed to me that all the recommended books are out of print.
Can anyone give me a recommendation which _available_ book to get?

filtering lines in a table
Hello,
I realize this is probably a dumb question, but I think there must be an
easy way to do this with R and I was not able to find it in the doc.
I have a table (read from a file with read.table), with two factor
columns, table$A and table$B, and a numerical column, table$X. I wish to
make a boxplot of (table$X ~ table$A) for a given value of B. Is there
a way to express this with a

3d in R
Dear R-users and R-developpers,
I've not been able to find 3d graphics in R, like
Splus spin() or brush(). Are there any that I've missed
and/or is anybody working on implementing these
type of functions?

nlme errors ?
Dear friends. Below is ouput directly from the help on qqnorm.lme.html
It do not seem to work as expected - on win98, R 1.1, although the
regression is undertaken, so qqnorm

attaching data to any object
Hi,
is the following possible - in a given session I make a lot of objects
and save when exiting. Usually I note down seperately what each object
is about. Is it possible to attach data to any object which would
essentially be a short note explaining the meaning of it?
Thanks,

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

Problems with levels of factors
Dear R-helpers,
I frequently run into problems when I modify elements of factors (R 1.0.0,
Linux 2.0.25). For example, after splitting a data frame accordinng to
whatever criterion, it might well happen that not all levels of a factor
are present in all new data frames. However, R doesn't seem to care about.
When performing some kind of analysis seperately on the new frames, each
time the

Strange behavior using .Fortran
Hello everybody,
I observed some strange behavior of R (0.64.1/Linux 2.0.25) when trying
to use FORTRAN-libraries.
I downloaded "ALGORITHM AS 304" from StatLib. All I changed at
the code, was to substitute "REAL"-routines by "DOUBLE PRECISION".
Compiling went o.k. ...

shame on me if I have overlooked something (CRAN, StatLib), but I think

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.

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

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

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/).

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.
