--- title: "Basic Plots" author: "Jeff Goldsmith" date: 2019-09-10 output: html_document --- ```{r setup, include = FALSE} library(tidyverse) ``` 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. ```{r df_create} 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. ```{r x_hist} ggplot(plot_df, aes(x = x)) + geom_histogram() ``` Next we show a scatterplot of `y` vs `x`. ```{r yx_scatter} ggplot(plot_df, aes(x = x, y = y)) + geom_point() ```
