I edited the Windows system environmental variable "Path" and the user environmental variable "PATH" (wasn't sure which to edit), to contain the follwing after a semicolon "C:\Program Files\gs\gs8.54\bin\". This effectively fixed the Dos box problem. I now get a GS prompt when I type gswin32c.

  I'm on WinXP Pro and the following puts test.tif on the Desktop for me:

bitmap(file='C:\\DOCUME~1\\CHARLE~1\\Desktop\\test.tif', type = "tifflzw", res = 1200)
plot(speed ~ dist)

  It does not work with spaces in the path.
