I found there's a very good functional set of operations in R, such as
apply family, Hadley Wickham's lovely plyr, etc. There's even a
Reduce (a.k.a. fold). Now I wonder how can we do pattern-matching?
E.g., now I split dimensions like this:
m - dim(V)[1] # R
n - dim(V)[2]

Using the list function defined here:

list[m, n] - as.list(dim(iris))
mylist - as.list(1:5)
list[Head, Tail] - list(mylist[[1]], mylist[-1])
