Okay, I've had it!!!.. Every time I read in a dataset using something like:
returnmatrix = read.csv("S&P.csv", header=TRUE, sep=",")
It comes back with "returnmatrix" as mode list. How can I quickly convert the dataset to mode numerical? This is pissing me off. I can do it manually by creating a new matrix and assigning values of the list matrix to the values of the numerical matrix element by element, but it's time consuming. What can anybody recommend me?
