An example Knitr/R Markdown document

A minimal R Markdown example

A quote:

Markdown is not LaTeX.

To compile me, run this in R:

library(knitr)
knit('001-minimal.Rmd')

See output here.

code chunks

A paragraph here. A code chunk below (remember the three backticks):

1+1
## [1] 2
.4-.7+.3 # what? it is not zero!
## [1] 5.551115e-17

graphics

It is easy.

plot(1:10)

hist(rnorm(1000))

inline code

Yes I know the value of pi is 3.1415927, and 2 times pi is 6.2831853.

math

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 knitr::knit2html().

nested code chunks

You can write code within other elements, e.g. a list

  1. foo is good

    strsplit('hello indented world', ' ')[[1]]
    ## [1] "hello"    "indented" "world"

  2. bar is better

Or inside blockquotes:

Here is a quote, followed by a code chunk:

x = 1:10
rev(x^2)
##  [1] 100  81  64  49  36  25  16   9   4   1

conclusion

Nothing fancy. You are ready to go. When you become picky, go to the knitr website.
