Try:
ggg <- c("F","M","F",M")
data$gender <- factor(ggg[data$gender])
This in effect converts the (spurious) " F" and " M" levels into "F" and
"M" respectively, giving you a factor with the two levels that you
really want.

There are two issues here. First, your original factor seems to have 4

Just to add that the op's data$gender has 4 levels, not just 2. So it
would be better to remove the leading spaces from " F" and " M", by

Thanks Jeff. That doesn't explain it for me. Could you go through the
algorithm a step at a time to show why it splits at the individual
characters rather than the words, perhaps privately. Feel free to

"\\b" is a zero length match. strsplit seems to chop at least one character off
the beginning of the string if it sees a match, and then it looks at the
shortened string that remains and repeats.

Note that John's solution probably includes incorrect partial matches
and that mine fails to match "red" in "this is red." If you change my

it should agree with Jeff's. Note, however, that you have mi
