I'd like to include the levels of one of my variables in the title of a
plot. I'd like these factor levels to be concatenated. E.g. 'These are
the levels: setosa, versicolor, virginica'.
I've been working with this code but I don't get the desired results.
Any suggestions would be a great help. Thanks!
dd <- iris
main=sprintf("These are the levels: %s", levels(dd$Species)))
