Carol,
  Take a look at the cut() function.

Hi,
I have an integer vector that I want to convert to a categorical vector
with values 1, 2, 3. 
If the value of an element of the integer vector < 20, then, the value
of the corresponding element in the categorical vector will be 1 
if the value of an element of the integer vector > 20 and < 50, then,
the value of the corresponding element in the categorical vector will be
2
if the value of an element of the integer vector > 50, then, the value
of the corresponding element in the categorical vector will be 3

can I do this by switch and how

look forward to your feedback

carol
