...ecdf(), but dealing with the censored data is quite hard-working in this case. Is there anything for censored data in ecdf like-functions or a way to adapt plot.survfit to my case?

...being passed to the panel and hence the output of the function survfit is not the expected one. Is there a way to plot this correctly, ie, having first the survfit computed and then the plot, like in: plot(survfit(Surv(time,event)~groups,data=B),log=true) Thanks in advance. - Marco. -- Marco Chiarandini http://www.imada.sdu.dk/~marco Department of Mathematics Email: marco AT imada.sdu.dk and Computer Science, Phone: +45 6550 4031 University of Southern Denmark Fax: +45 6593 2691

...replications was the same for all experimental units. I would like to know if someone in the list had a similar experience and if what I am doing is correct. In alternative also a reference to another list which could better fit my request is welcome.

Dear list, perhpas this question is more suitable for R-dev but since I am not really a developer I post it here first. Apparently the following lines do not create any problem in R: library(combinat) r <- 20; b <- 2; sum( sapply(0:r,function(x) nCm(r,x)^(2*b)) ) > 2^64 while in C I obtain an overflow of data even using unsigned long long and with long double I incurr in precision

Hallo, is there any extension of the pairwise Wilcoxon test to a dependent samples layout with replicates (or, in other terms, a one-way layout with blocking and replicates)? The Wilcoxon method with matched pairs works for the case of dependent samples with one observation per block, while the Mann-Whitney test works for independent samples, thus one single block and replicated observations. Is

Hallo, I would like to organise at my pleasure the layout of a trellis plot. Currently I have a 3x3 matrix display and 7 plots. Is it possible to choose which specific panels will stay empty? I tried index.perm to arrange the order. Then there is perm.cond which I could not understand if it can serve for my purpose since I cant really find which kind of data it accepts. Thank you for the help.
