+
+## Objectives
+
+- Understand the grammar of ggplot
+- Apply aesthetic changes to a plot
+- Visualize a distribution
+- Visualize a relationship between variables
+- Explain
+
+## Questions
+
+- How can I plot my data?
+- What type of plot should I use for my data?
+
+
+Today we're going to learn how to plot in R using ggplot2.
+This is a package designed to streamline the production 
+of complicated and aesthetically pleasing plots. You can also
+make plots in R without ggplot2, but its easier to learn ggplot2 
+and almost any plot can be constructed with it.
+
+We first have to login to the <b>VPN</b> and then the [Rstudio Server](https://indri.rcs.uvic.ca/)
+in your browser. We already installed most of the tidyverse packages
+last lab (go back to lab 3 if you didn't do that). Today we're going to install
+a few more packages used in the tutorial
+
+```R
+#This has example data for plotting
+install.packages("palmerpenguins")
+#This has different themes for designing your plots
+install.packages("ggthemes")
+
+```
+
+Then we want to load all the packages. We're doing this instead of loading
+tidyverse (which has issues on our system)
+
+```R
+library("dplyr")
+library("ggplot2")
+library("nycflights13")
+library("forcats")
+library("stringr")
+library("readr")
+library("tibble")
+library("tidyr")
+library("purrr")
+library("stringr")
+library("palmerpenguins")
+library("ggthemes")
+```
+
+Now we're going to work through [Chapter 1 of R for Data Science](https://r4ds.hadley.nz/data-visualize).
+
+If you finish Chapter 1 early, [Chapter 9](https://r4ds.hadley.nz/layers) 
+extends into more complicated plots.
