r: boxplot names="" with single vector

Question

I cannot get names to work in box plot. Is it not working because I only have a single vector? Heres what I have tried.

tmp = c(1,1,1,1,2,2,2,2,5,5,5,5,5,6,5,4,7)
boxplot(tmp)
boxplot(tmp, names=c("today"))
boxplot(tmp, names="today")
boxplot(tmp, labels="today")
boxplot(tmp, labels=c("today")

Answer 1

boxplot(tmp, names=c("today"),show.names=TRUE)
