R Markdown training
Data Visualization Notes
This is a starter RMarkdown project template to accompany courses taught with Data Visualization. You can use it to take notes, write your code, and produce a good-looking, reproducible document that records the work you have done. At the very top of the file is a section of metadata, or information about what the file is and what it does. The metadata is delimited by three dashes at the start and another three at the end. You should change the title, author, and date to the values that suit you. Keep the output line as it is for now, however. Each line in the metadata has a structure. First the key (“title”, “author”, etc), then a colon, and then the value associated with the key.
The training documents are RMarkdown Files
Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. A code chunk is a specially delimited section of the file. You can add one by moving the cursor to a blank line choosing Code > Insert Chunk from the RStudio menu. When you do, an empty chunk will appear in your file.
Code chunks are delimited by three backticks (found to the left of the 1 key on US and UK keyboards) at the start and end. The opening backticks also have a pair of braces and the letter r, to indicate what language the chunk is written in. You write your code inside the code chunks. Write your notes and other material around them, as here.
