Enter the following command in R to read a simple help page about the table() command (this is for your information, you do not need to show the output):

?table

Now enter the following command and describe the output of the table() command. What does the first row of numbers in table() output represent? What does the second row of output represent?

x <- c(5, 8, 4, 1, 5, 6, 5, 9, 4, 2, 5, 7, 5, 3, 6, 4, 5, 3, 7, 6)

table(x)

[optional: You can test your theory by altering the numbers and rerunning the table command.]
