It was my understanding that the output may contain several pages of plots, and I don't know of a bitmap device in R which can do that.

Re: [R] Flattening Graphics
Hi baptiste auguie wrote: Hi, You could try the grid.grab() function in R devel if your graphics use the Grid package. It will read the graphical output as a bitmap which grid.grab() does NOT grab a bitmap version of the current picture. It grabs all of the (grid-rendered) grobs in the current picture. You might be thinking of grid.cap(), which is currently only in the development version of R. But if you want a raster version of the current plot, it would make more sense to use a raster device, like png(). Paul you can then export in a multipage pdf. It may not be really flattening per se but that would definitely help with the viewing speed.

Re: [R] Flattening Graphics
Hi, You could try the grid.grab() function in R devel if your graphics use the Grid package. It will read the graphical output as a bitmap which you can then export in a multipage pdf. It may not be really flattening per se but that would definitely help with the viewing speed.
