Hi!
I am troubled by Sweave which I want to use in order to plot graphics which
I build up successively by the use of grid.layout. Here is the code:
<<fig=TRUE,label=evolDist,height=6in,width=3in,pdf=FALSE>>=
## combined plot via grid viewports
grid.newpage()
pushViewport(viewport(layout=grid.layout(2,1)))
vlay <- function(x,y) viewport(layout.pos.row=x, layout.pos.col=y)
print(pl$gscoreDist, vp=vlay(1,1))
print(pl$acceptDist, vp=vlay(2,1))
dev.off()
@
The error is the following from Sweave:
Error in grid.newpage() : Non-finite location and/or size for viewport
In addition: There were 24 warnings (use warnings() to see them)
Error in driver$runcode(drobj, chunk, chunkopts) :
Error in grid.newpage() : Non-finite location and/or size for viewport
Calls: Sweave -> <Anonymous>
Execution halted
Any hints? Of course, I can always wrap the code into a fig=FALSE, and
pdf()-call, but that is not how sweave is meant to be used, as I got it.
Many thanks in advance,
Sebastian Weber
