Hey,
I wrote a loop and want to save plots of multiple
SpatialPolygonDataFrame objects with something like
png(paste("K:/Outarde/ADrien/FigTemp/PGR",l,"_",j,".png",sep=""),
height=1000, width=2000,res=300)
b<-spplot(grTs[,c("PGRobs04","PGRobs48")],
col.regions=palAb(30)
dev.off()
and
png(paste("K:/Outarde/ADrien/FigTemp/Abondance",l,"_",j,".png",sep=""),
height=1000, width=3000,res=300)
spplot(grTs[,c("ov2000","ov2004","ov2008")],
col.regions=palAb(17),at=cutsAb)
dev.off()
When I run "manually" the code (specifying the l and j values for the
loop), everything is fine and I get nice png files. When the code loops
on its own, I get blank images. I suspect this is a problem of the time
taken by spplot to build the image in time for saving in the loop.
Is this correct and how can I properly overcome this problem ?
Best regards
Alex
