[R] Sweave: Avoiding recompilation of figures

[julia.jacobson at arcor.de]

Hello everybody out there using Sweave,

There are some complicated SQL queries and laborous calculations against large data included as R code chunks using Sweave in my LaTeX document.
These code chunks create graphs that do not change most of the time, but they are of course recompiled every time I run Sweave on my file for update of minor changes to the LaTeX text.
Is there an option implemented in Sweave allowing for avoidence of recompilation of already existing figures?

Thanks in advance,
Julia
