How do I use NROW in R?

The function nrow in R has the form nrow(dataset). This will return the number of rows in the data set. This replaces the need for complicated solutions such as iterating across the elements to count them. Using this example of the mtcars data set, nrow in R shows that this data set has thirty-two rows.

How do you find out what a percentage of something is?
