Hi,

This is my first post to R-help.  I'm having trouble getting rgeos to work.

Info on the server and packages I'm using:

$ *uname -a*

gDstnc> p1 = readWKT("POLYGON((0 0,1 0,1 1,0 1,0 0))")

gDstnc> p2 = readWKT("POLYGON((2 0,3 1,4 0,2 0))")

gDstnc> gDistance(pt1,pt2)
R: GeometryComponentFilter.cpp:34: virtual void

I'd like to be able to use the gDistance function.  What should I do to fix
this?

Please let me know if any additional information would be helpful.

Thank you for your time,

Adrian
