Dunno. Maybe \captionof{listing} ? Or let minted do its thing ? Anyway,
in most cases, the code excerpts will be too long for a float ; the
idea is to send them (unfloated but labeled/captioned) in an appendix
and point to them via a link.

[ BTW : we should stop suggesting to use listings, which is problematic
for anything not strictly ASCII, bloody likely to occur at least on a
comment/prompt for most of mankind... Listingsutf8 is but a patch
working only for (a subset of) European languages. Arabic, Hebrew,
Asian languages : nope. Minted in (xe|lua)tex is probably more usable
(but needs --shell-escape, which can justifiably frowned upon... ].

Attached.

But please coordinate with Bastien, who asked me just yesterday to
avoid posting fat attachments to a message going to a lot of people.
Which I did (to no avail : the "heavy" mail went through anyway. Go
figure.... ;-).

You're welcome ;-). Thank YOU for considering scratching *MY* itch...

The R block 1 generates the figure 1:

Figure 1: Figure generated by R

Listing 1: R code generating a figure

curve(sin(x),from=-pi, to=pi)

Problem: whereas the HTML export labels the source listing as "Listing 1" and is correctly refers to 1, the PDF export labels it "Figure 2" (and points to it).
