[datatable-help] R - Comparison

Hello everyone,

I have a vector X = [ 0 2 5 4 1 9 ]
I want to build another vector Y  wich will have the same length as X and
which contains the comparison of the elements of x as follows :
if x < = 3: returns F
if 3 < x < = 6: returns M
if 6 < x: returns E

I expected the result:
Y = [F F M M F E ]

How to do that with R ??

Thank you :-)
