Adding REPLACE_R+=

[Makoto Fujiwara <makoto%ki.nu@localhost>]

I'd like to add
  REPLACE_R+=
function (* 1)

but the attached patch is not enough,  ${R} is empty for now, say,
  make show-var VARNAME=R
returns empty.

Please let me know or just commit the correct changes
There may be discussion whether r/R should be lower or upper case in this patch,
anyway thank you,

(* 1)
textproc/R-vroom  1.5.4
wants this function, it is the new package, by the way,
(Is it good that wip version to be placed on wip/ ?)
