Welcome to StackOverflow and R. First I would start with:

> library(help = "datasets")

This tells you a little about the available datasets in this package.

This package is part of the base R installation, and you don't need to load it. If you're curious where these datasets are stored on your machine, you can enter:

> system.file("data",package = "datasets")

For more info on the state datasets, you can enter: ?state This tells you that state.division is one of the datasets available in this package. 

> str(state.division)

However, it won't make a lot of sense without some additional context, so try something like:

> head(df <- data.frame(state.abb, state.division, state.x77))

           state.abb     state.division Population Income Illiteracy Life.Exp Murder HS.Grad
Alabama           AL East South Central       3615   3624        2.1    69.05   15.1    41.3

Arkansas          AR West South Central       2110   3378        1.9    70.66   10.1    39.9

With a data.frame you should have the context you need to start make interesting plots or models, for example a linear regression model:

summary(lm(Murder ~ state.division + Illiteracy, data=df, weights=Population))
