A minimal R Markdown example
Markdown is not LaTeX.
To compile me, run this in R:
See output here.
A paragraph here. A code chunk below (remember the three backticks):
1 + 1
##  2
0.4 - 0.7 + 0.3 # what? it is not zero!
##  5.551e-17
It is easy.
Yes I know the value of pi is 3.1416, and 2 times pi is 6.2832.
Sigh. You cannot live without math equations. OK, here we go: $\alpha+\beta=\gamma$. Note this is not supported by native markdown. You probably want to try RStudio, or at least the R package markdown, or the function
nested code chunks
You can write code within other elements, e.g. a list
foo is good
strsplit("hello indented world", " ")[]
##  "hello" "indented" "world"
bar is better
Or inside blockquotes:
Here is a quote, followed by a code chunk:x = 1:10 rev(x^2)
##  100 81 64 49 36 25 16 9 4 1
Nothing fancy. You are ready to go. When you become picky, go to the knitr website.
