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,
Rui Barradas

Hello,
please, I need to calculate the indicator function as I underlined in my
attached pdf file but I can't define a code in programming language that
deals with this case. Please help me with a code whether it's in python or
R can help me.
Sincerely.
