The current plot is saved to a temporary image file using dev.copy. This file is then written to the workbook using insertImage.

)A workbook object
A name or index of a worksheet
Width of figure. Defaults to 6in.
Height of figure . Defaults to 4in.
Alternate way to specify startRow and startCol. A vector of length 2 of form (startcol, startRow)
Row coordinate of upper left corner of figure. xy[[2]] when xy is given.
Column coordinate of upper left corner of figure. xy[[1]] when xy is given.
File type of image
Units of width and height. Can be "in", "cm" or "px"
