Postscript viewer

plot is not part of the core of the language -- it is a program written in Shang. Shang does not have built-in graphical capabilities. The figures produced by the plot program are postscript files and need a viewer to be displayed and printed.
  1. Install postscript and ghostview on your computer so that postscript files can be viewed, printed, and converted to other formats. For MS Windows, the programs can be obtained from

  2. Run plot.x before making any plot. This can be done manually or putting with("plot.x") in your program.
