R help - Apr 2009 - Creating datasets in packages

I am developing an R package which includes datasets. The build and
install works correctly. However, when I access the dataset
("BowRiver"), I get:
 
> data(BowRiver)
> BowRiver
Error: object "BowRiver" not found. However, I can access the dataset
from 
> data
 
Example R datasets (such as USArrests) are loaded and can be accessed by
the dataset name:
 
> data(USArrests)
> USArrests
               Murder Assault UrbanPop Rape
Alabama          13.2     236       58 21.2
Alaska           10.0     263       48 44.5
Arizona           8.1     294       80 31.0
Arkansas          8.8     190       50 19.5
California        9.0     276       91 40.6
...
 
What am I doing wrong?
 
Thanks in advance,
Dave

The key question:

We don't know what you _did_. How did you save the data?
Did you follow the directions in the Writing R Extensions
manual? Does ls() show the dataset? etc.

You can "access the dataset from data" - do you mean
that you can load the data directly from the data directory
within your package? How?
