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
