You could try:

   as.matrix( read.table( filename ) )

Subject: [R] loading matrix from file 

What is the best way to load a matrix from a text file if it's already
in a matrix form? I'd like the parser function to automagically
recognize that line separators indicate a new row. The technique I've
been using is the following:

output <- matrix(scan(inputFile), byrow=T, ncol=2)

However, I don't want to have to specify ncol=2.
