There are many, many ways to do this, depending on what you're really after.
Here's one:
depts = levels(factor(zidl$dept))
for (i in 1:length(depts)) {
tiny.dataset = subset(zidl, dept==depts[i])
# now do whatever processing you need with tiny.dataset
}
Read the Introduction to R and the help page for the subset command,
i.e., ?subset
