Try this;
cut(x, breaks = c(0, 10, 20, 100), labels = c(0.3, .5, 1))

Hi Jarek,
Take a look at ?which, ?ifelse and ?recode (car package).
HTH,

Unless someone happens to be a Mathematica user (very possible), I don't know
how we would answer the question. You give an

well function arguments are in square brackets. z is result (new
vector). I show Matematica syntax, but cannot explain what I expect. Sorry
The example is wrong because it can be replaced by R cut function. The
arguments are: condition,action and can be replaced by ste of ifelse
formulas:
well thanks, when I post the mail I thought I got too simple example
which may be really replaced by "cut", but I thought about little more:
let say:
z = Which[x<10,x/3, 10<=x<20,0.5, 20<=x<100,x^2/(x-1)]
where there are both values and formula
sorry for mismatch and thanks for quick answer
Ja
