Hi José

Have you seen the result of 
as.integer(factor(myfile$groups))) ? I would have given you a clue.

What you need is c("black","white") or the 
numerical col number equivalent by the order of the groups.

2 ways:

ifelse(myfile$groups == factor1, "black","white")

or if you had more factors

sapply(myfile$groups, pmatch, unique(myfile$groups) )
