Hm. I just added x11() to the script snipped of yours:
edd@sonny:~> cat /tmp/R.sh
#!/bin/sh
echo | R -q --no-save <<EOF
bitmap("test.png")
plot(1:10)
graphics.off()
x11()
EOF
but starting this under at(1)
edd@sonny:~> echo /tmp/R.sh | at now
warning: commands will be executed using /bin/sh
job 57 at 2001-11-18 08:31
yields an error:

Error in X11(display, width, height, pointsize, gamma, colortype, maxcubesize) :
unable to start device X11
Execution halted
How does Solaris do this, and how can we get Linux to do the same?
