Submission from: (NULL) (

let A be a mtrix with n lines and p columns, p>36 ;

matplot(A) will only draw the plot of the first 36 columns of A.

This is due to a bug in the definition of pch in the function : 

pch <- c(paste(c(1:9, 0)), letters)[1:k]

should be replaced by 

pch <- c(paste(c(1:9, 0)), letters)

I hope this is clear, 

All the best,
