Include levels of zero count in result of table()

Viewed 23544

I have a vector 'y' and I count the different values using table:

y <- c(0, 0, 1, 3, 4, 4)
table(y)
# y
# 0 1 3 4 
# 2 1 1 2 

However, I also want the result to include the fact that there are zero 2's and zero 5's. Can I use table() for this?

Desired result:

# y
# 0 1 2 3 4 5 
# 2 1 0 1 2 0
