Re: [PATCH] ob-R output file with graphics parameter

["Berry, Charles" via "General discussions about Org-mode." <emacs-orgmode@gnu.org>]

Sorry if I have misunderstood the proposals here, but ...

A user might like to construct a figure consisting of various subfigures such as in a subfloat environment.

Will this be reasonably simple to accomplish if `:results graphics' (with no `file' element) automatically inserts a link?

Currently, omitting the file element leaves the link out, which I believe is the most direct way to approach subfloats.

If you deem it important to have the default behavior of `:results graphics` generate a link, maybe you can assure that there is a mechanism to avoid inserting the link when that is what the user wants.

Best,
Chuck
