Error in ratingmat[current_user, ] : subscript out of bounds about goodbooks-10k HOT 4 CLOSED

simply changing current_user to "8" makes this part run. Because its the first row name and neither 7329 nor 17329 exist in row names. that 7329 is dependent on random seed but no numbers go above summary(as.integer(rownames(ratingmat))) 10000

from goodbooks-10k.

glimpse(ratingmat)
summary(as.integer(ratingmat@Dimnames$user_id))
Min. 1st Qu. Median Mean 3rd Qu. Max.
8 13427 26638 26841 40486 53407

What was I supposed to do? Is there some setting I could change? BUT

any( (ratingmat@Dimnames$user_id)=="17329")
[1] FALSE
any( as.integer(ratingmat@Dimnames$user_id)==17329)
FALSE

from goodbooks-10k.

BUT THEN max(users==17329), even any(sample_users==17329) =1
perhaps you intended to use base::as.matrix instead of Matrix::as.matrix?
