 Now, let's save it. I'm going to call my file `ggplot2.Rmd`.
 
-OK. Now let's practice with some of those commands that we were working on this morning.
-
-Create a new chunk in your RMarkdown first in one of these ways: 
-
-- click "Insert > R" at the top of the editor pane
-- type by hand 
-   \```{r}
-   \```
-- if you haven't deleted a chunk that came with the new file, edit that one
-
-Now, let's write some R code. 
-
-```
-library(tidyverse) # install.packages('tidyverse')
-```
-
-Now, hitting return does not execute this command; remember, it's just a text file. To execute it, we need to get what we typed in the the R chunk (the grey R code) down into the console. How do we do it? There are several ways (let's do each of them):
-
-1. copy-paste this line into the console.
-1. select the line (or simply put the cursor there), and click 'Run'. This is available from 
-    a. the bar above the file (green arrow)
-    b. the menu bar: Code > Run Selected Line(s)
-    c. keyboard shortcut: command-return
-1. click the green arrow at the right of the code chunk
-
-### Your turn
-
-Add a few more commands to your file from this morning. Execute them by trying the three ways above.
-
 Then, sync your file to GitHub.
 
 What if a file doesn't show up in the Git tab and you expect that it should? Check to make sure you've saved the file. If the filename is red with an asterix, there have been changes since it was saved. Remember to save before syncing to GitHub!
