That doesn't need to be a problem, an alternative that works with this
feature is:

na.strings = "DNA", header = TRUE)

We can leave it as a factor when being read in, and then relevel it
easily by "converting" it to a factor and specifying the levels using
the in-built constant/vector 'month.name'.
