You should provide us with a data example.

In the following, the two solutions are completely different but both of 
them do what you want. Note that the second creates a factor variable, 
whose levels are coded as integers. See R-intro.pdf in your doc 
directory, chapter 4 Ordered and unordered factors.

x <- sample(c("Male", "Female"), 10, replace = TRUE)

y1 <- ifelse(x == "Male", 1L, 2L)
y2 <- factor(x, levels = c("Male", "Female"))

Hope this helps,
