RODBC connection failed
I am trying to restart on R after 2 months stop. Start with previously
functioning procedure:
"ch<-odbcConnect("dBase Files")"
get
"Warning message:
ODBC connection failed in: odbcConnect("dBase Files") "
I have tried unsuccessfully different working directories.
The only change I see is that I am working with a new login account on
the same machine.

Windows / RODBC / Accented characters
A disturbing behaviour of R: an import of data using RODBC library
(Windows 98, R 1.1.1) recognizes accented characters in variables
names but these can't be manipulated further. See below:
> library(Rodbc)
> ch<-odbcConnect("Paradox Files")
> pollut<-sqlFetch(ch,Pollutio)

Multiv / hierclust / plclust
I use hierclust (hierarchical clustering) in multiv package. In the
documentation it is said that plclust (plotting a dendrogram) is
available in S-plus. Can I find it anywhere (I have searched through
http://lib.stat.cmu.edu/S and found only quotations of plclust in
multiv) or is it only part of the S package (which I don't have)?
Thanks

Memory management
Some naive questions:
1) How to remove a column in a data frame? I expected that rm would
work but this is not the case (e.g. rm(dat$yyy) gives Warning
message: remove: variable dat$yyy was not found). I only found to
assign NULL value (e.g.: dat$yyy<-NULL). Is it the right way?
2) Is the place formerly occupied by dat$yyy automatically gained by
R for other uses?
3) If t1 and t2 are 2 only

3D perspective of a contingency table
How can I draw a 3D perspective of a contingency table, that is
showing 3D bars whose height is in proportion of the table cells?

ploting axes plaxes ?
I used in previous versions of R (R 1.1) to plot axes on projections of
factorial coordinates using the function plaxes. This doesn't exist any
more. Why this change ? No alternative ?

plot history, libraries, weights
3 general questions:
1) How can I have the plot History Recording automatically turned on
each time I start R (Windows)?
2) How can I have some libraries automatically loaded at R start?
3) As far as I know weights can be specified only for lm. How can I
take account of weights with a weighted sample in other models or
functions (table but also other multivariate and cluster techniques)?
Thanks

plot of a cut
I have made a cut of a numeric vector and try to plot it. However
only half of the x-axis annotations (the labels) appear on the plot,
apparently because of the font size. I have tried cex.lab, cex.axis
(what is the difference?) etc. The x labels are never printed
whatever value I use from 0.0005 to 20. I can't obtain a way to
make all the labels appear correctly. Between the short help

Writing a workable function
After searching in R- Introduction, FAQ, help... I don't understand
this:
I write a function in a file (.R):
tt <- function(mc) { date()
mc<-read.csv2("machines.txt",na.strings="")
date()
}
I source it in R and I type tt(). The answer is
> tt()
[1] "Mon Aug 14 11:18:25 2000"

The instructions following the first "date()" are ignored. Why?

transforming table into data frame
Hello,
I would like to transform a contingency table (A x B) into a data
frame while keeping the cross-tabulation structure (i.e. rows =
levels of A, columns = levels of B). I have tried as.data.frame,
xtabs, etc... and always got a "flattened" list of 3 variables (A, B,
Freq).
How to do that?
Thanks in advance

k-means / role of 'nstart'
Hello,
the k-means {stats} help and the Hartigan&Won paper say nothing about
the way random sets works (parameter nstart). I would expect to get
the different results for each random initial set but I always obtain
only one result: how is it selected?

PDE
Dear all,
Does any know how to solve PDE with R? The archive list refers to the
use of ODE if PDE are parabolic. I am not a mathematician and this does
not mean anything for me!
help would be very appreciated.
Many thanks

Problems with graphics
Dear all,
I am a SAS user, who's trying R. I am a little bit lost for graphics.
What is the simplest way for plotting y as a function of x with one
symbol (line or dot) for each level of a class variable z (for SAS
langage= plot x*y=z). Can I add vertical bars for standard deviation
stored in a separate variable (say ystd). Finally, is it possible to
do all this with xyplot function

Installing lumi and hdrcde
To whom it may concern.
As I would like to analyse some array data I was keen on downloading the
lumi package that depends obviously on hdrcde that is not available for r
2.12.1. I did not find instructions to solve or circumvent this problem.
Installing hdrcde by hand did not work either. It was not detected by
> (.packages(all.available=TRUE))
if installed in the R library.

amd detect answering machine
Hi,
I have IVR and when I press 1, asterisk calls my mobile phone.
If my mobile phone is offline, asterisk transfers to asterisk voicemail.
I'd like asterisk detects my mobile voicemail and if my mobile voicemail answers, asterisk transfers to asterisk voicemail.
For that, I used AMD.
So I have problems ! Asterisk detects answering machine everytime!
How do I do please ?
