Thanks, but that was what I just discovered myself the hard way.
What I really wanted to know was how to solve this issue.
Although that was _not_ what you requested in your first post.
2 options:
?table
?factor
iris1$Species <-factor(iris$Species) # removes "extraneous" levels
And that was not what I meant to type. Meant for factor to be applied
to second dataframe.:
iris1$Species <-factor(iris1$Species) # removes "extraneous" levels
