Hi all,

I have some data x, which are actualy consisted of numerical enties. But the class of this matrix is set to be "factor" by someone else. I used "class(x)", it turns out to be "factor". So I can not calculate them.

How can I turn them into numerical data so that I can apply math operations on them? Thanks a lot for your help.

Selina
