Since mle is defunct is there anyother function I can use for maximum likelihood estimation ? Thanks ../Murli

Hi !! Is there a good tutorial for the R language ? I really find it hard to find methods in R. Thanks and Cheers ../Murli

Any package that implements Random matrix theory application in R. I am completely new to this subject, so just wanted to explore it. Cheers ../Murli

Is there an option to draw concentration ellipses in biplots ? It seems really nice to summarize large number of points of each group. Cheers../ Murli

When using the biplot how do I supress the column names from appearing in the plot. I am only interested in the plot with the arrows. When I use xlabs =NULL nothing gets plotted. Thanks ../Murli

How do I get the labels from a hclust object after I have cut the tree using cutree ? hc<-hclust(someData,"a") branches<-cutree(hc) If there are two branches, how do I obtain the labels associated with each of...

Just to explain my previous mail, here is the output I get. > dim(tissue.exp) [1] 1532 20 > pick<-sample(tissue.exp,5,replace=TRUE) > dim(pick) [1] 1532 5 > tissue.exp.t<-t(tissue.exp) > dim(tissue.exp.t...

I am trying to sample a subset from a matrix using sample. The size of the matrix is 20X 1532. It works fine with this, but when I transpose the matrix and try to sample it, it returns null. pick...

Is the swiss data set in R the same as S dataset swiss.x . I was trying out some clustering by doing the following that I got from Venables and Ripley's book. h<-hclus(dist(swiss.x), method= "connected...

Hi !! I need to generate plots from several multiple file and I am doing this by reading it as a list using c(file1, file2.....). Since I need to either print the plots or save it as an plot image...

Is there an R function that I can use to calculate the p-value from the Z statistics computed for the relationship between chance and observed proportions in predictions. More sprcifically I am refering to proportional chance criteria (Cpro). Details...

I am using the hier.part package for calculating the goodness of fit. Before I started with my data I tried to use the example that the package comes with . I have loaded the library hier.part and gtools. But...
