Hi,

It works fine for me. The error that you got suggests that the data file
could not be parsed properly. Maybe a problem with your R installation? Or
internet access from R? Or default format for date?
The data file it downloads from the fred website only has two columns - a
date and a value. Like this:
DATE,VALUE
1919-01-01,4.8502
1919-02-01,4.6358
1919-03-01,4.5019
...

             INDPRO
1919-01-01   4.8502
1919-02-01   4.6358

1919-04-01   4.5822
1919-05-01   4.6090
