install problem
Dear R experts,
I am in transition to the R system from other statistical systems I was
using (SPSS, Statistica, etc.). I have used R for a few months on my
Windows PC, but now I would like to install R on a Linux box with SuSE 8.1.
I downloaded the RPM for SuSE 8.1 from the CRAN mirror.
But when I run the INSTALL script using the midnight commander it gives
the following error message:

Sweave scientific real display format (e.g. 5e-12)
Dear All,
I couldn't figure and couldn't google out how to make construct a pair of
\Sexpr s or a LaTeX macro that would include
5\cdot 10^{-12}
into the LaTeX output istead of
5e-12 .
Any ideas?
Thank you

R demonstration ideas?
Dear All!
Tomorrow morning I will have to demonstrate R to a professor here at the
Semmelweis University. He uses Windows and Statistica. I will have 20
minutes and I would like to convince him that R is powerful, and it even
could be used in teaching the students basic medical statistics.
Could you give me some ideas what to show him in this 20 minutes?
This night I will have about 1.5 hours

special characters
Dear R-users,
Some hours ago I successfully installed R 1.7.1 on my Linux computer
(SuSE 8.1). Now I am trying to get my scripts work which I have written
for R/Windows.
* While with Windows I was able to use the vowels with the accents
present in the Hungarian language:
> d$crude.inc<-d$esetsz?m/d$?vk?zepi.l?leksz?m*1000000

the same line leads to an error on Linux:

Dear List,
Could you tell why I get the error message?

tick marks: 0, 12, 24, 36 ...
Dear R-help list,
I have a problem with the tick marks of a Kaplan-Meier survival plot.
Here is a sample:
follow.up<-c(10,20,30,40,50,60,70,80,90,100) #months
dead<-c(1,1,1,0,1,1,0,0,0,0)
KM <-survfit(Surv(follow.up, dead))
plot(KM)
The result is a nice plot. However, our research group thinks it may be
a better idea to place the ticks to the years on the time scale, i.e. 0,

numerical differentiation in R? (for optim "SANN" parscale)
Dear R users,
I am running a maximum likelihood model with optim. I chose the
simulated annealing method (method="SANN").
SANN is not performing bad, but I guess it would be much more effecive
if I could set the `parscale' parameter.
The help sais:
`parscale' A vector of scaling values for the parameters.
Optimization is performed on `par/parscale' and these
