Note: This approach has not been widely tested!
This markdown document was created from an R Markdown (Rmd) document compiled to HTML through knitr with the keep_md: yes set in the preamble of the Rmd document.
The following is an extension of the familiar sample R Markdown document. The example code below shows how we can source the textormd() function available here.
#source('~/repos/textormd/textormd.R')
source('C:/Users/mienkoja/Dropbox/repos/textormd/textormd.R')Having sourced this function, we can then call our desired latex math code inline textormd("\\textstyle \\frac{d}{dx}e^x=e^x") (See this link for more information about inline R code in R Markdown documents).
When the R Markdown document is compiled to HTML (in knitr with keep_md: yes in the preamble) the inline code will result in the following typeset math text: 
along with your R code and R graphics as shown below.

When this process is performed in a local Github wiki repo (see the link here), the resulting markdown document can be pushed to the live repository (along with your math png files and any other figures). The markdown documents will then appear in your repo as wiki pages along with the typeset math font and any other images you push to the wiki repo.
More details on the how to specify your tex can be found in the mathtex documentation here.
