更改 R 中 `table()` 输出中的字符名称？

Question

I was wondering how I could change the name foo appearing in the top-left corner of the output of b in my R code below to boo ?

foo <- sample(rep(1:3, 20))
b <- table(foo)
b

I tried the following with no success:

names(b) <- "boo"

You can set the character name using the parameter dnn.

foo <- sample(rep(1:3, 20))
b <- table(foo, dnn = "boo")
print(b)
#boo
# 1  2  3 
#20 20 20
