[R-sig-Geo] spTransform problem

[stephen sefick]

I am having problems with spTransform in packages rgdal.  If this is
not enought information please let me know and I will send whatever
you need.  It doesn't seem like it is avaliable.

library(rgdal)
w <- (new("SpatialPoints"
    , coords = structure(c(33.31665, 33.31834, 33.3239, 33.37435, 33.36018,

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
