Use the single # to make a new heading

Use the double ## to make a new subheading

use the tripple ### to make a new sub-subheading

any text you write will be treated as text, not executable code

you can format text by surrounding it with special characters:

1. bold
   
2. italics

note that the above text will be formatted into a numbered list. You can also make bullet lists:

• be sure to start each bullet with a * followed by a space
• be sure to leave a blank line above the first item in your list

you can even include urls. rmarkdown help

lastly, you can write text chunks
    these will be printed within a box to
 your document with   whatever    formating you 
 like. *special characters* won't do anything.

code chunks

you can add a code chunk using the following syntax

# everything you type in here works just like a regular r script
data(cars)
str(cars)

## 'data.frame':    50 obs. of  2 variables:
##  $ speed: num  4 4 7 7 8 9 10 10 10 11 ...
##  $ dist : num  2 10 4 22 16 10 18 26 34 17 ...

hist(cars$speed)

# note that you can evaluate your code chunk using the green arrow keys at the top right corner

inline code example

you can also add snippets of r code to text using this syntax: the mean speed of cars was: 15.4.
