Be sure to change the type of this chunk to You can use this dataframe in R code chunks to perform analysis or to generate a ggplot, for example:Naming code chunks can be useful for long documents with many chunks. Here are some of the essential R Markdown shortcuts: Insert a new code chuck with Command + Option + I on a Mac, or Ctrl + Alt + I on Linux and Windows.
