cluster, GFS on DRBD and dissimilar hardware such as Xeon and duo core
assuming sufficient memory is available on the target.
TIA
Thanks and Regards,

estimate the number of clusters
...ters in a microarray
dataset.
Initially, I used the iris data to test my piece of code as follows:
library(cluster)
data(iris)
mydata<-iris[,1:4]
maxk<-15 # at most 15 clusters
myindex<-rep(0,maxk) # hold the si values for each k clusters
mdist<-1-cor(t(mydata)) #dissimlarity
mdist<-as.dist(mdist)
for(k in 2:maxk)
{
hc<-diana(mdist,diss =TRUE, stand = FALSE)
si<-silhouette.default(cutree(as.hclust(hc),k=k),mdist)
myindex<-summary(si)$avg.width
}
myk<-rev(order(myindex))[1] #select the number of k clusters with the...

randomForest outlier
I try to use ?randomForest to find variables that are the most important to
divide my dataset (continuous, categorical variables) in two given groups.
But when I plot the outliers:
plot(outlier(FemMalSex_NAavoid88.rf33, cls=FemMalSex_NAavoid88$Sex),
type="h",col=c("red","green")[as.numeric(FemMalSex_NAavoid88$Sex)])
it seems to me that all my values appear as
