Perhaps the following?

d <- structure(list(x1 = structure(1:4, .Label = c("a",
"c", "e",
"g"), class = "factor"), x2 = structure(1:4, .Label =
c("b",
"d", "f", "h"), class = "factor")),
.Names = c("x1", "x2"), class "data.frame",
row.names = c("1",
"2", "3", "4"))

with(d, c(as.character(x1), as.character(x2)))
#  [1] "a" "c" "e" "g" "b"
"d" "f" "h"

HTH,
Jorge.-
