Hi,
Another option that you might want to try is the tikzDevice package;
tikz has functions to flip and rotate objects and could it from R with
tikzAnnotate / tikzAnnotateGrob. Of course these objects would not
really be grobs but tikz code, though for text the end result would
probably be the sam
My question was answered off list by Paul Murrell, author of 'grid'. Here's am
excerpt of our email exchange for the records of R-help.

In some special cases, you would be able to "flip" shapes. If the
coordinates of the shapes are given in "native" coordinates,
Oops, sent too early; this obviously just a rotation, not a mirror
image. It illustrates the problem though ;)

You can rotate the viewport to flip around the horizontal axis,
library(grid)
grid.text("Chiral")
grid.text("Chiral", vp=viewport(angle=180, y=unit(0.5,"npc")-unit(1,"line")))

Maybe my question was not concise enough. I was referring to objects created
with the "package "grid" (also called "grobs"), not to the function "grid"
from package "graphics". For instance, let's say I have a polygon createad
with grid::polygonGrob and want to mirror it along a specified axis.
Hello,
Just flip 'xlim' or 'ylim'. Or both.
Using the iris example in help("grid"), make the following changes:
op <- par(mfcol = c(2,2)) # Two columns, first is the original, second
flipped.
with(iris,
[... etc ...]
# row 1, col 2: flip x axis
plot(Sepal.Length, Sepal.Width,
Hi everyone
I'd like to flip grobs (grid graphical objects) along an axis, e.g. flip grobs
horizontally or vertically. I couldn't find any hints, neither in the
documentation nor by searching the web. Does anybody know how to achieve this?
Cheers
