Having a look at the roulette grid, one can see that 10 out of the 18 red numbers are odd. Will we be able to spot this relationship from the random drawings? We will investigate this visually. We plot the proportions of red and the proportions of even numbers using a scatterplot (lines 3 to 6). The main argument set the title of the graph (line 4). The xlab argument sets the title of the horizontal axis (line 5). The ylab argument sets the title of the vertical axis (line 6). We also add and a line (called slope) showing the direction of the relationship using abline() function on line 7.

The Packages menu contains functions that allow installing and loading packages, as well as the configuration of local and distant repositories. Useful functions of the Packages menu include the following: • Load package: Provides a frontend for the library() function, which loads a package provided as an argument. • Install packages: Allows selecting a package to install. This requires configuring a mirror for CRAN first. • Install package(s) from local zip files: Opens a dialogue box in which a ZIP file containing a package can be selected for installation in R.

Df) } We are now able to examine the relationship between proportions of numbers using scatterplots. Scatterplots display each observation on a plane by plotting the values of two attributes. On line 1, we first create a data frame of proportions using the default arguments for multisample() function. This will not take too long to compute. Having a look at the roulette grid, one can see that 10 out of the 18 red numbers are odd. Will we be able to spot this relationship from the random drawings?
