Even prettier: the Mosaic Plot

The table command can be used to tabulate any number of variables that you provide. This means you can investigate how different categories relate to each other. For example, you can see how many people have smoked at least 100 cigarettes in the different general health groups by executing

table(cdc$genhlth, cdc$smoke100).

Go ahead and try this in the console before starting of with the challenges.

To have a nice graphical representation of this distribution you can use the mosaicplot() command.
