Thanks so much for your answer. I had (of course) to install nvim in order the
code to work, but this works ! Thanks also for your additional work regarding
the locale setting.. this is really deep magic for me.
I think the facility to run R code directly from context can open ConTeXt to
new users. The alliance between R and LaTeX is a winning combination to a lot
of my colleagues. Do you think this would be appropriate to do a simple page on
the wiki explaining how R code can be done in ConTeXt, with eventual
formatting, with some simple examples, or this is too much noise ?
Thanks. Fabrice.
