Welcome to the UBCadv-r wiki!

This wiki is intended to be an easy way for people to share their answers to exercises. It is especially great if you do not want to upload your whole set of notes to Github. Just click Edit in the top right of this page to edit the page. You may contribute answers to the wiki whether or not you are also sharing your notes.

Writing in Markdown

You can use the buttons at the top of the edit window to format your writing. Alternatively, you can use the Markdown syntax directly.

  • Headings are prefixed with one or more # symbols. The more # you add, the smaller the heading. e.g. # Heading 1, ## Heading 2, etc.
  • Bold is wrapped in double asterisks: **bold text here** = bold text here
  • Italics are wrapped in single asterisks: *italic text here* = italic text here
  • Links are created by wrapping the text in square brackets followed by the URL in parentheses: [Click here](http://www.virusreleaser.com) = Click here
  • Inline code is designated with back-ticks (the one on the top left of your keyboard, under the ~): `library(magrittr)` = library(magrittr)
  • Code blocks can be designated by putting three back-ticks at the start and end of the block:
> ```
> x <- c(1:5)
> x[NA]
> ```

Gives you:

x <- c(1:5)
x[NA]
  • Quotes are done with a side carrot: >To the man who only has a hammer, everything he encounters begins to look like a nail. =

To the man who only has a hammer, everything he encounters begins to look like a nail.

  • You can create a horizontal line with three asterisks: ***

  • And a bulleted list (like this one) just by prefixing each item in your list with one asterisk: * item 1 ; * item 2
  • A numbered list is create by prefixing the items with any number: 1. item 1 ; 2. item 2 or 1. item 1 ; 1. item 2. The numbers will automatically be put in the correct sequence, but sometimes markdown can't figure out that you are still creating a list if there are too many carriage returns or code chunks between list items. In that case, your numbering will just be screwed up no matter what.
