Hi, how to do quickly equivalent of the following? counter = 0 for(i in 1:length(data$S2)) { if(!is.na(data$S2[i])) { counter = counter + 1 } } I have imagined something like length(x,na.rm=TRUE). How can I get values usually taken from tables like z-score, values of t distribution etc.? I could not find them among values mentioned in info file. Thanks, Matej -- Matej Cepl,

Hello, From repo, the lastest release 2.0.11-0~auto+32 does not have ldap support :/ auth: Fatal: Support not compiled in for passdb driver 'ldap' Regards, Stephane

I have to solve a clustering problem. My first step is to determinate the number of clusters, that's why I 'm using the Calinski index ( [tr(b)/(k-1)]/[tr(w)/(k-1)] ) which i try to maximize to have the best number of clusters. A function is already implemented in R to calculate this index : clustIndex(cl,x, index="calinski") where cl is the result of a clustering method ,
