Hi all, If I want to write a for loop to loop through a set of factors, which are not coded in 1,2,3, for e.g in character, possible to write the for loop without changing it to categorical variables? I saw the manual mentions for loop will take a list, but I'm not sure how to create a list here. Any input will be appreciated. Thanks. Yen Lin [[alternative HTML version deleted]]

[R] Loop through factors without changing to numerics
An example would have helped to give you a better answer. You can use
characters in the "seq" argument of the for loop. i.e
x=letters[1:4]
x
[1] "a" "b" "c" "d"
for(i in x) {print(i)}
[1] "a"
[1] "b"
[1] "c"
[1] "d"
Is this what you were looking for?
