[R] counting the frequencies of a vector

[Jörg Groß]

Hi,


Is there a function which counts the frequencies of the occurence of a  
number within an interval?

for example I have this vector:

x <- c(1, 3, 1.2, 5, 5.9)

and I want a vector that gives me the frequencies within an interval  
of 2, beginning at 0
(so the intervals are 0-2, 2-4, 4-6 and so on)

so I get these frequencies:

2, 1, 2


Which functions do I have to use for this purpose?
