...veryone, R beginner, I am confronted with the need to use Rmpf. In my first scripts I made use of X=read.table(file.choose(), header=FALSE, sep=",",dec=".") X=as.matrix(X) to load into a matrix data from file before matrix use. How can I do to load the same data in a "mpfrMatrix". Is it possible to use with "mpfrMatrix" the same as operations M1%*%M2 scale(M1,TRUE,FALSE) Sorry but I'm a newbe Thanks in advance Michel [[alternative HTML version deleted]]

Hi, I'm working on an S4 class that is expected to behave like an array. I have some difficulties when defining '[' and I wonder if someone could point me to the right direction: 1) Call the S4 object "obj" 2) Assume dim(obj) = c(10, 4, 2) 3) Suppose someone calls: obj[1:3,] , which is a mistake, given dim(obj); how do I detect such situations? Thank you very much for
