Have the counter function in R ?
if we use the software SAS
/*** SAS Code **/
data tmp(drop= i);
retain seed x 0;
do i = 1 to 5;
call ranuni(seed,x);
output;
end;
run;
data new;
counter=_n_; * this keyword _n_ ;
set tmp;
run;
/*
_n_ (Automatic

Subject: [R] Have a function like the _n_ in R ? (Automatic count function
I think you can use seq function:
seq(5)

The _n_ construct in SAS is most analogous to that of row names in R,
accessible (and modifiable) via the row.names() function:
DF - structure(list(Month = structure(c(2L, 2L, 2L, 2L, 1L, 1L, 1L,
1L, 3L, 3L, 3L, 3L, 3L), .Label = c(Aug, July, Sept), class =
factor),
Week = 27:39,
And for completeness here's a function that returns the next integer
on each call.
n - (function(){
i - 0
function() {
i - i + 1
i
}
})()
n()
[1] 1
n()
[1] 2
n()
[1] 3
n()
[1] 4
n()
[1] 5
n()
[1] 6
