[R] Reading from Google Spreadsheets with RGoogleDocs

[Farrel Buchinsky]

I cannot read google spreadsheets. I get the following error:

assignment of an object of class "NULL" is not valid for slot "access"
in an object of class "GoogleSpreadsheet"; is(value, "character") is
not TRUE

RGoogleDocs is on the cusp of brilliance. How can I troubleshoot this
apparently last remaining problem?
