cor_disc has 415264 rows.

Error in where(is.na(as.numeric(cor_disc[[1]]))) :
   could not find function "where"

Searching for 'where' in ?read_csv finds only
where each character represents one column:

And, if there was such a non-numeric in any row of column 1 wouldn't
read.csv() also catch it and throw an error?
