dev.capture  Capture device output as a raster image  Description dev.capture captures the current contents of a graphics device as a raster (bitmap) image.  Usage 
dev.capture(native = FALSE)
 Arguments  
native  Logical. If FALSE the result is a matrix of R color names, if TRUE the output is returned as a nativeRaster object which is more efficient for plotting, but not portable. 
  Details Not all devices support capture of the output as raster bitmaps. Typically, only image-based devices do and even not all of them.  Value NULL if the device does not support capture, otherwise a matrix of color names (for native = FALSE) or a nativeRaster object (for native = TRUE).
