I always get lost in simpleKey. The approach of directly modifying
the trellis object usually works.

+ 'p', pch = 19, key = simpleKey(text = levels(ffg.st$func_feed_grp), space =
+ 'right', points = T, lines = F),par.settings = list(superpose.points =
+ list(col = rainbow(7)), superpose.lines = list(col = rainbow(7))), main =
+ 'Functional Feeding Groups (Individuals)', xlab = 'Year', ylab = 'Proportion
+ of Individuals')
