The ConTeXt module for interaction with the statistical programming language R currently does not work with MKIV since buffers are not saved to file. The included file fixes this by calling \savebuffer on the buffer in case \ctxlua is defined (a trick gleaned from a discussion on the LilyPond module a while back). Also, all calls to R used to include a rather annoying proc.time() statement at the end, and a modified R call has fixed this. PATH must contain R or R.exe on Windoze. Should 'texmfstart' still be used for the R calls? A third modification involves being able to call \startRnoecho (which only echoes R output in the ConTeXt file) in addition to \startR (which echoes both input and output) and \startRhidden (which echoes nothing, useful for generating graphics) One further improvement would be to collect the R snippets and run them all at once. That would significantly reduce processing time since the R startup is on the order of a few seconds. However, that is beyond my knowledge of ConTeXt.
