[R] split variable / create categories

[Martin Batholdy]

Hi,

is there a function or an easy way to convert a variable with continuous values into a categorial variable (with x levels)?

here is what I mean:


I want to transform x:

x <- c(3.2,  1.5,  6.8,  6.9,  8.5,  9.6,  1.1,  0.6)

into a 'categorial'-variable with four levels so that I get:

[1] 2 2 3 3 4 4 1 1

so each element is converted into its rank- value / categorial-value
(in this example four levels are created).



thanks for any suggestions!
