The purpose of this file is to present a couple of basic plots using
ggplot.
First we create a dataframe containing variables for our plots.
set.seed(1234)
plot_df = tibble(
x = rnorm(1000, sd = .5),
y = 1 + 2 * x + rnorm(1000)
)First we show a histogram of the x
variable.
ggplot(plot_df, aes(x = x)) + geom_histogram()## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
Next we show a scatterplot of y vs x.
ggplot(plot_df, aes(x = x, y = y)) + geom_point()
