# RMarkdown to WordPress

One option is to create your markdown document in R, using $$\LaTeX$$, knit to html, then copy the file content into WordPress and add at the top the following javascript code:

<script type="text/javascript"
src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>

This will load images into the blog post itself and preserve the $$\LaTeX$$ formatting. I prefer to use the MathJax-LaTeX plugin, and use the MathJax CDN Service, without having to add the javascript to every post.

Use the latex2exppackage to translate expression to $$\LaTeX$$ form, that can be added to plots, eg. axes labels or equations in notes.

library (latex2exp)
library(ggplot2)
ggplot(mtcars) + geom_jitter(aes(x=disp, y=qsec)) + ylab(TeX("\\frac{a^e}{b_x}")) + xlab(TeX("\\prod_{x}^{y}"))
latex2exp_supported(plot = T)

What does NOT work:

Have tried direct export but it does not work. It uses RWordpress, and logs in directly. Still needs the above javascript to preserve $$latex$$ formatting, and needs additional gymnastics with the plot images. Some additional discussion here.

## Math

Test the Math equation rendering: Inline formula with $$a=3$$ and $$b=5$$ $x = a + b$

## Table

knitr::kable(data.frame(a=1:5,b=rnorm(5)))

The easiest way to post your R markdown directly to WordPressis following Tobias Dienlin‘s method (or many others).

Create a separate publish.R file that will upload your post:

if (!require('knitr')) {install.packages("knitr")}
if (!require('devtools')) {install.packages("devtools")}
if (!require('RWordPress')) {devtools::install_github(c("duncantl/XMLRPC", "duncantl/RWordPress"))}

library(knitr); library(RWordPress)
