[S] Points inside a polygon

[mwand@hsph.harvard.edu (Matt Wand)]

  Dear List Members,

  I'm interested in obtaining S-PLUS code for
  determining which members of a set of points
  are inside a specified polygon.

  Could you please let me know if you
  have or know of such code?

  thanks,
  Matt
