[R] How to show classes with 0 count in table()?

[R. Michael Weylandt]

It's not a totally general solution but something like

table( factor(x, levels = min(x):max(x)))

will do it in this case. The key is to make understand that R converts
your data to a factor if necessary and then checks each level of that
factor. Here we are taking care of the factor conversion explicitly.
