[![Build Status](https://travis-ci.org/cdupont/R-pandoc.svg?branch=master)](https://travis-ci.org/cdupont/R-pandoc)

A [pandoc](http://johnmacfarlane.net/pandoc/) filter to embbed R plots inside markdown documents.

See the [Blog post](http://www.corentindupont.info/blog/posts/Programming/2015-09-14-diagrams.html) for more details on usage.

## Usage

Install R:

    sudo apt-get install r-base


Create a file called [demo.md](demo.md) with the following text:

``` markdown
Here is a nice plot:
    ~~~ {.Rplot}
    require(stats)
    D = 150
    T = 10
    t = seq(0, 80, 0.01)
    x = -D*exp(-(t/T))+D
    v = (D/T)*exp(-(t/T))
    plot(t, x, type="l", main="position through time", xlab="time (s)", ylab="position (m)", xlim=c(0,80), ylim=c(0, D+10),  xaxs = "i", yaxs = "i")
    ~~~
```

Now run:
``` shell
    pandoc -t html demo.md --filter R-pandoc -o demo.html -s
```

The file demo.html should now have a nice plot included:

![plot](img/Rplot.png)


## Details

`R-pandoc` compiles code blocks containing R plots
and includes the resulting images in the pandoc markup.  It is meant
to be run as a
[pandoc filter](http://johnmacfarlane.net/pandoc/scripting.html) as
shown above.


## Installing


``` shell
    git clone https://github.com/cdupont/R-pandoc.git
    cd R-pandoc
    stack install
```
