Hi

one of my packages [1] has several places in its vignette where multi-panel 
figures are generated via the likes of "par(mfrow=c(4,2))" within <<fig=TRUE>> 
code chunks. The package builds fine with 'R CMD build', and the vignette 
builds fine when calling Sweave manually. However, 'R CMD check' fails with
* checking running R code from vignettes ...
   ‘Hiiragi2013.Rnw’ ... failed
 ERROR
Errors in running code in vignettes:
[..snip..]
  When sourcing ‘Hiiragi2013.R’:
Error: figure margins too large

I believe this is because R CMD check calls Stangle on the .Rnw and then 
sources the .R file disregarding any device size settings. I can think of 
several ways to work around this, but this seems like a rather basic deficiency 
of the current system that asks for a more generic answer. Does anybody have 
any insight here?

        Best wishes
        Wolfgang

PS I am sorry if this has been discussed elsewhere, but digging in the R-exts 
manual and in Google did not turn up a solution for me.
