FUN in the aggregate is a built- in function such as : mean, sum etc.
Can I have smth like:
```
func <- function(x) {
y <- (data.frame(x$Species, mean(x$Sepal.Length), stringsAsFactors =
FALSE))
}
aggregate(iris, FUN=func, by=list("Species"))
```
This doesn't seem to work and R doesn't demonstrate examples on that either.
Also R speaks about FUN as " summary statistics function" for us it can be
anything applied on grouped data.
