Knitr/Rstudio etc

The r-derived entrant in the scientific workbook field.

Hmm. RStudio offers web service, both and IDE and shiny, their general app service. There must be some commercial hosting options for these?

Here are some guides:

For online web-friendly (e.g. teaching) purposes, you can do literate interactive coding using shiny and latex via shinytex.
