[R] convert Splus mapproject() in R

[Huiqin Yang]

Hello everyone,

  I was wondering if anyone knows how to convert the Splus mapproject( ) function for use in R, I would greatly appreciate your help. I am using the following system, R
Version 1.6.1  (2002-11-01) for SunOS 5.5 and  Splus  Version 5.1 Release 1 for Sun SPARC, SunOS 5.5.

Thanks, 

Helen
