If I am understanding your example correctly, you actually redo the R
calculations each time you compile the LyX document. Is that a desired
feature, or would you be just as happy running the R code once and
parking the generated table in the LyX document? I ask because elsewhere
in the thread I pointed out (in a reply to Riki) that one can use a
custom R function (which you could set up to load by default whenever
you crank up R) to convert a data frame or table to LaTeX and copy the
LaTeX code to the clipboard. After that, all you have to do is paste it
into your open LyX document using the correct LyX command, and it goes
in as a table.
