Because the following line is syntatically correct:
if (age <=10) {group == 1}
the R parser does not expect the following:
else (age > 10 & age <= 20) {group == 2}
else {group == 3}
causing a sytax error. Instead, you want:
if (age <=10) {
group == 1
} else (age > 10 & age <= 20) {
group == 2
} else {
group == 3
}
