Hello,
Please cc the list, R-Help is threaded and your doubt and answers might
be of interest to others.
With a vector Y, you want 0 in all Y != l and 1 in all Y == l?
n_l <- function(Y, l) as.integer(Y == l)
Hope this helps,

Hello,
Maybe this?
n_l <- function(Y, l, na.rm = FALSE) sum(Y == l, na.rm = na.rm)
set.seed(2020)
q <- 6
y <- sample(q, 10, TRUE)
l <- 4
n_l(y, l)
#[1] 3
Hope this helps,

please, I need to calculate the indicator function
Perhaps (in R):
n_i <- cumsum( Y==l )
You should read further regarding R's logical class, and operators that
work on it, and how it is coerced.

Is this a homework problem? The posting guide linked below explicitly says:

these."
