By "standard R editor" to you mean the RGUI editor that ships with R?
On my
Mac platform, it has menu entries in the "Format" menu that allow you to
choose different fonts and sizes. On Windows, of course, the menus may be
organized differently, but I would assume there's something similar.
If you
mean some other editor (e.g. see ?edit), then you need to dig into their
docs. Again, I assume something similar would be available.

I don't think it is available in Rgui.exe.  I believe that as Tim
describes, there's just one choice of font, you don't get "rich text"
like you do in the Mac R.app editor.

    But did font size *used* to be adjustable in Rgui.exe?  "I think that
this used to be possible"

    I don't know exactly where to look for changes, I was looking at
history of stuff in R/src/gnuwin32 (especially editor.h, editor.c) but
didn't get very far.  Maybe things also changed in the upstream Windows
libraries, i.e. Rtools → MINGW-w64, etc. ??


Look here:

  https://github.com/wch/r-source/blob/trunk/src/gnuwin32/editor.c

No sign of any big changes there. The last ones to talk about fonts or other display issues were in 2008.

Dear R development  Team
I am a long time user of R with a distinctly poor vision.  I have been
using the standard R interface for many years and am comfortable with it
except for one minor detail.  There seems to be no way to change the
font
in the standard R editor.  I think that this used to be possible and
would
like it to be brought back in future releases.  At the moment I have
many R
command files with font sizes that suit my needs.  By copying these and
renaming I can continue to work with fonts that I like.  It also
seems to
work if I start a new file in notepad and set the font size there.  I
can
then open this file in the R editor and the font size will be
retained.  At
the very least I would like to be sure that work arounds like this
remain
possible in any new releases.
Best
John Warner
