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="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML">
</script>
```

This will load images into the blog post itelf and preserve the \(\LaTeX\) formatting. Simple!

Source

Use the `latex2exp`

package 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)))`

a | b |
---|---|

1 | -0.0499999 |

2 | -1.6248843 |

3 | -0.9676244 |

4 | 0.9533118 |

5 | 0.6553010 |

## Plot

The following plot shows the annual blog frequencies and serves as example of a succesful file upload.

```
library(ggplot2)
ggplot(mtcars, aes(x=factor(cyl), y=disp)) + geom_jitter()
```
