Dear all, I would like to plot n time series together. I've defined a matrix w, where each column contains one time series. With S-Plus usually I use the tsplot(.) command, but it seems that this command is not available in R. Can someone help me?

I hope that someone can help me with the following question: I would like to solve the Markowitz optimization problem WITH short-sale constraints. Maybe a procedure to solve a quadratic optimization problem with convex constraints and positive variables is already implemented in R?

Sorry for the silly question. I am trying to perform a simple operation on a subsample of my data loaded as data and attached: data<-read.dta(name file) attach(data) Say x=1,2 and y=4,5 I want to summarize z only if x=1 & y=4. I thought that the way to do that would be to write if((x=1) & (y=4)) summary(z) butwhen I do this the result I get is for the whole data (irrespective of

I recall someone had fixed the rbconfig.rb to get it working. Is this something I still have to do? 2. Does anyone know if Locomotive is using the uniersal binaries, or is it targetting PPC yet? I couldn''t
