Creating datasets in packages

In developing the package, I have associated datasets (*.rda) stored in the data sub-directory. I built and installed the package successfully.

When I load the BowRiver dataset and USArrests

data(BowRiver)
data(USArrests)
ls()

[1] "data"      "USArrests"

Why is mine stored as "data" and not "BowRiver"?

The key question:

What am I doing wrong?

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?

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

What am I doing wrong?

Thanks in advance,
