[R-sig-Geo] testing a crs string

[Roy Mendelssohn - NOAA Federal]

Hi All:

I am extending a package I have to allow users to provide a crs string, which will eventually through some other packages be sent to sf.  I like to try and make at least minimal tests that inputs are valid.  Is there some existing code that will check if a string is a valid crs string?

Thanks,

-Roy
