In that case, use > n <- dim(Z) > n [1] 8 4 or, if you only need to store the number of rows in Z, use > nrow <- dim(Z)[1] > nrow [1] 8 Instead of nrow, the variable name zrow may be more appropriate. As you would expect, similar to the cbind function to arrange the variables in columns, the rbind function combines the data in rows. 7 This gives the same data as in the previous examples, with the morphometric variables in rows and the individual birds in columns.
