[R-sig-Geo] [R] Help with simple Map of US states with predefined regions Version 2

Thu Sep 13 20:31:55 CEST 2018

Thank you Jeff.

Cannot seem to get this to work in the fashion I want it to appear no matter how many websites and packages I investigate.

Letting it go for the moment.

Always appreciate your advice Sir!

Your data appear to be in fixed format, not space-delimited (or delimited by any other special character), so you should use read.fwf to read it in rather that read.table.

?read.fwf

In the future you should try to identify where your errors are or your data don't look right and ask focused questions about that (reproducible) problem rather than spilling your whole script into an email. That is, your error occurred in the single read.table command and the rest of it was working fine.
