Greetings all: OK, this is bugging the @[EMAIL PROTECTED] out of me. I know the answer is simple and straightforward but for the life of me I cannot find it in the documentation, in the archives, or in my notes (because I know I've encountered this in the past). My problem is:
I have a data frame with columns A, B, C, D, and E. A, B, and E are factors and C and D are numeric. I need a new data frame with just A, C, and D. When I copy these columns to a new data frame >newDF <- data.frame(cbind(oldDF$A, oldDF$C, oldDF$D)) all the factor data comes out as levels rather than the original factors. How do I preserve the factors when I copy from one data frame to another?
