# [R] postscript (eps) / latex / par(mfg=...) / problem!

Namely that using par(mfg=...) with a postscript (eps) for inclusion with latex makes the figure appear upside down and back to front (flipped)!

Converting the dvi to ps makes matters worse (the eps seems to be broken), however, it appears fine with gv.

Here is (basically) the code I am using...

>t(dat)

+           height = 6.0,
+           horizontal = FALSE,
+           onefile = FALSE,
+           paper = "special",
+           )

>par(mfg=c(1,1))
>par(mar=c(3,4,1,2))
>plot(dat,type='b')
>
>par(mfg=c(2,1))
>par(mar=c(4,4,0,2))
>plot(dat,type='b', log='y')
>
>dev.off()

Including the resulting file in a latex document like this...

begin{figure}

\centering
\includegraphics[width=\textwidth]{x.eps}
\caption[X]


{
Hello!
}
\label{xFig}
\end{figure}

The result is an upside down (flipped) version of my plot. I tried rotating 180 degrees (based on similar problems people were having on the list), but then it just gets worse (most of the plot is off the page). If I convert the dvi to ps (dvips -Ppdf my.tex.dvi -o my.tex.ps) it gets worse (a tiny speck where the image should be).

After removing the two mfg commands (which I use to add grid lines (not shown for clarity)) everything is fine! Some how mfg is snarling things up.

OK, I just had a brain wave (dont laugh). Here is a diff of the working eps vs the broken eps...

Does that help anyone debug my problem? Like I said, both look identical
via gv, and are 'conceptually' identical in R.
