[R-pkg-devel] Internet resources and Errors

[Roy Mendelssohn - NOAA Federal]

try/stop is in the operational code.  But it is easy enough to make it so that the code always returns something, even when there is an internet access problem.

As I said,  if  "failing gracefully" and ever actually been defined with examples life would have been much easier for a number of packages developers.
