From what I understand, they would like to import a .Rds file without
having to manually convert it to LaTeX.
Scott,
Definitely correct on the "without" part. But we want to directly
import an R object
of class data.frame or data.table into an LYX table.
If we have to export such an object first, we would typically export
it to an .Rda object.
But it would be far more convenient to not have to do that.

Doug,
I'm not sure that what you want (direct import without first exporting)
is possible. Keep in mind that the source data frames / tables live
inside an R session, to which LyX probably does not have access. So I'm
pretty sure you will need to manually export the R objects, either by
saving to .Rda files (and then importing them into a LyX document using
a converter) or by running an R function/script that converts them to
LaTeX or LyX source (or something else LyX can ingest).
Note that if you do your R work in an IDE, such as RStudio, you could
probably set up an addin / plugin / <whatever your IDE calls it> to do
the export by invoking a shortcut.
