[R] Changing selected columns to factor

R-Help Forum If I have a data frame consisting of say ten (10) variables (A,B,C,D,E,F,G,H,I,J) and I want to change Variables 2,7,8,and 9 to factors is there a command such that I can do it in one line or do I simply have to convert each separately? Jeff [[alternative HTML version
