I am writing a function in R and have an input id that is a numeric vector.
Can I write a for loop that states:
for(id in id)
{
/****/
}
and loop over the id vector with the variable id or will this cause problem?
It will produce the expected result but it will destroy the id to the right of the in. Also within the loop all references to id will be the id to the left of in so you won't be able to reference the one on the right.
> id <- 1:3
> for(id in id) print(id)
[1] 1
[1] 2
[1] 3
> id
[1] 3
Try writing it like this to be safer:
ids <- 1:3
for(id in ids) print(id)
