Your question should have been posted to the R-sig-geo mailing list.

FWIW I have no direct experience with the files or functions you are using, but I have to say the error message seems pretty clear to me: latitude values are normally limited to [-90,90], but your file appears to have data outside this range. Thus, the file appears to have invalid data.
