I get + signs in front of monames and labels, again as expected, but then it
gives me another + sign. And if I try to add another ), it keeps giving me +

Is this what you are looking for?

I have a dataframe comprising a vector of E. coli concentrations, a vector of
months when the samples were taken, and a vector of sampled sites. I�d like to
produce a lattice with sites along the horizontal axis, and months on the
vertical. Each site-month box would then contain concentrations
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,

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:

Go to page http://zzz.bwh.harvard.edu/plink/profile.shtml and follow the
help to generate a basic allele score using your independently associated
SNPs. Use R to make the myprofile.rawfile required.
I am unable to generate .raw file which will contain allele score
I have tried this script:

You have already asked this and people gave you a variety of answers.
Just asking again without clarifying why those answers did not help you
is not going to solve your problem.
Tell us what you tried and why it failed might help.
