[R-sig-Geo] Make function ignore +inf and -inf values

[Edzer Pebesma]

You can't expect such behaviour from analysis functions; this is a 
problem in your data or introduced by your analysis (e.g. taking logs 
from zero values). I believe the job of the data analyst (you) is to 
solve this before you call the analysis functions / methods.
