[R] basic table statistics

[Walmes Zeviani]

You can use fBasics package

sample(c("A","B","C"),size=20,replace = T) -> type
rnorm(20) -> value
data.frame(ty=type,val=value) -> test

require(fBasics)

nam <- rownames(basicStats(test$val))
result <- do.call("cbind", with(test, tapply(val, ty, basicStats)))
rownames(result) <- nam
result

Bests.
