[R] Letters(V1,V2..) as row col indices instead of numbers

[kparamas]

What makes matrix to print V1, V2 as the row and col indices instead of
numbers??

cdata = read.table("ramesh.txt") #cdata is read from a file.
c1 = cor(cdata) 

I am printing c1 below. I need only numbers. I dont need V1, V2...what
should I do in this case??
