I don't understand most of what you wrote, but when you say "matrix" you are
mistaken. A matrix is NOT the same thing as a data frame, which is what you get
when you call read.csv(). Read
RShowDoc("R-intro")
Sections 5 and 6... A data frame is a list of column vectors, while a matrix is
a vector with a dimension attribute.
You can use the as.matrix function to convert a data frame to a matrix.
