Converting coordinates to actual distances
...tual distances between points, and taking into account the curvature of the earth. Is there such a package in R? I've looked at the GeoR package, but this does not seem to contain what I am looking for. Ideally the output would be a triangular matrix of distances.

Generating start values for nls
...ce has been to make estimates from a priori knowledge of the data. However, in the Matlab CurveFit tool, reliable start values are somehow estimated 'heuristically', as is claimed in their help files. Is there a similar R routine than may produce reasonable start values?

opendap/dods data retrieval
Hello, I was wondering if there has been any progress in developing a package for accessing opendap/dods data using R. I see from the list archive that there was some initial work done on this.
