Plots

This document produces basic plots.

The first code chunk sets the seed to ensure reproducibility, and creates x and y variables.

set.seed(1234)

x = rnorm(1000)
y = 1 + 2 * x + rnorm(1000, 0, .4)

Next we use a code chunk to produce a histogram of x. The fig.width and fig.height options control the size of the resulting plot.

hist(x)

Next we show a scatterplot, similarly controlling the figure size using options.

plot(x, y)
