[R] Passing a LaTeX length to Sweave

[Thomas Levine]

Darn. Well here's what I'll do

%Preamble
<<lengths>>=
columnwidth=whatever the \columnwidth is
@

%Figures
\setkeys{Gin}{width=\columnwidth}
<<label=something,fig=TRUE,echo=FALSE,width=columnwidth,height=0.3*columnwidth>>=
plot(y~x)
@

It needs to be exact so that the line weight and point size are
consistent across figures and with the text.
