You do not need to use ordered factors.
newfac <- factor(oldfac, lev= ...) ## will do it. e.g.
x <- factor(letters[1:3]) ## default ordering is alphabetic (mod locale)

Levels: a b c
y <- factor(x,lev=letters[3:1]) ## reorder the levels
y
[1] a b c
Levels: c b a
Bert,
Makes sense. I wonder if this will work when only a portion of the site
IDs need to be explicitly ordered. There are 64 sites in all. Might be
easier to sort the text file.
Thanks again,
Rich
