Please help me
Hi, The following code, from Angelo Canty article on line "Resampling Methods in R: the boot Package, 2002", works fine for Angelo Canty using R 2.6.0 on Windows XP.
It also works for me using R 1.2.1 and S-PLUS 2000 on Windows XP after installing the S-PLUS bootstrap library, with slight differences in my outputs.

Hi there,
I'm trying to install the package RcppArmadillo in my R 2.11.1 which I installed
and regularly update via Ubuntu's repositories.
When I try to install RcppArmadillo from CRAN I get:

Viable Approach to Parallel R?
All,
We are researching approaches to parallel R with the end goal of running
R in a distributed manner on a Linux cluster. We expect of course to do
some work decomposing our problems to be task-parallel or data-parallel,
but wouldn't mind getting an initial boost working with "embarrassingly
parallel" code sections and one of the approaches below.

plot(pam.object) error with R-1.7.0 on Red-Hat 8.0 i686
I don't know if there is some fault in compiling or a bug of the new
R-1.7.0 version:
cl.pam.2 <- pam(as.dist(1-cor(mel.data)),2)
plot(cl.pam.2)
perform a right partitioning and silhouette plot on the old R-1.6.2
instead
"Error in clusplot.default(x$diss,...... ;
x is not numeric"
is the output on the new R-1.7.0.
Same platform: RH8.0 i686.
Some suggestions?

R Crashes when using "large" matrices (Ubuntu 11.04)
Sorry for re-posting, but the original one ended up inside a previous and unrelated thread. -- Matias
-----
Hello,
This simple SVD calculation (commands are copied
immediately below) crashes on my Ubuntu machine (R 2.13.0). However it
works fine on my Windows 7 machine, so I suspect there's a problem with
(my?) Ubuntu and / or R. Can anybody else reproduce it (with Ubuntu
11.04)? Thanks

"order" issue
Hi everybody, this is a real dummy thing.
I sorted a matrix based on a given column, and what I get is right, until it comes to columns of negative and positive values; than, "order" orders everything from max to min in the negative values, and then AGAIN from max to min in the positive values!!!
Why isn't everything order from max to min, and that's it?
Thank you!!!

help on drawing right colors within a grouped xyplot (Lattice)
Hi,
I've lost my mind on it... I have to scatterplot two vectors, grouped by a third variable, with two different dimensions according to whether each cell line in the plot is sensitive or resistant to a given drug, and with a different color for each of 9 tissues of origin.
Here's what I've done:

I would like to use R function 'selectFGR' of fine gray model in competing risks model. I used the 'Melanoma' data in 'riskRegression' package. Some of the variables are factor. I get solution for full model but not in variable selection model. Any advice how to use factor variable in 'selectFGR' function. The following R code is produced below

selectFGR vs weighted coxph for internal validation and calibration curve- competing risks model
Dear Geskus,
I want to develop a prediction model. I followed your paper and analysed thro' weighted coxph approach. I can develop nomogram based on the final model also. But I do not know how to do internal validation of the model and subsequently obtain calibration plot. Is it possible to use Wolbers et al Epid 2009 approach 9 (R code for internal validation and calibration) . It is

(Censboot, Z-score, Cox) How to use Z-score as the statistic within censboot?
Dear R Help list,
My question is regarding extracting the standard error or Z-score from a
cph or coxph call. My Cox model is: -
modz=cph(Surv(TSURV,STATUS)~RAGE+DAGE+REG_WTIME_M+CLD_ISCH+POLY_VS,
data=kidneyT,method="breslow", x=T, y=T)
I've used names(modz) but can't see anything that will let me extract
the Z scores for each coefficient or the standard errors in the same

p-values
Dear All,
When I run rlm to obtain robust standard errors, my output does not include
p-values. Is there any reason p-values should not be used in this case? Is
there an argument I could use in rlm so that the output does
include p-values?
Thanks in advance,
