[R-sig-Geo] wkbMultiPoint and rgdal

I have an ESRI shapefile which has multi-point geometry, and I'm
trying to get it into R for use with sp() and raster().  Using:


Error in readOGR(dsn = getwd(), layer = "tnf_sub_2_TreeDig_pts_110725_v02",  :
  Incompatible geometry: 4
In addition: There were 50 or more warnings (use warnings() to see the first 50)

the warnings all say:
50: In readOGR(dsn = getwd(), layer = "tnf_sub_2_TreeDig_pts_110725_v02",  ... :
  eType not chosen

What I really want is to, in the end, have a SpatialPointsDataFrame
where each multi-point feature is converted to individual points that
have the attribute of what multi-point feature it came from.  What is
the best way to do this?  I'm attaching the zipped shapefile to this
email (hopefully it won't get bounced).
