"if" is not vectorised and "age" is a vector. Try the following test:
if(c(TRUE, FALSE)) "TRUE" else "FALSE"
You really need to use "ifelse".
ifelse(c(TRUE, FALSE), "TRUE", "FALSE")
As others have suggested, you might want to look at ?cut.

Hi everyone !
Could you please help me with this problem ?
I´ve trying to write a code that assign to a variable the content from
another, but all I´ve got is a message error. For example:
if (age <=10) {group == 1}
else if (age > 10 & age <= 20) {group == 2}
else {group == 3}
Syntax error

13 matches
