[R] Trellis Plots: translating lattice xyplot() to ggplot() [RESOLVED]

[Yihui Xie]

I guess you didn't tell us you were compiling the document with dvips
(BTW, I'm surprised that dvips is still alive today...), otherwise the
solution would be simply to use the postscript device instead of the
default pdf device (i.e. use the chunk option dev='postscript').
Hopefully you learned some lessons on what a reproducible example
means.

Regards,
Yihui
