R help - Apr 2005 - Creating packages with windows (accessing data)

Dear R List,

I have created a package (under Windows 2.0.1) with 300+ data sets and <20
or so functions I use in teaching.  However, to access the data, one needs
to type data(foo) once the package has been installed and loaded.  With
other packages namely MASS, after the package is installed and loaded with
library(MASS), it is possible to refer to a data set say Animals by simply
typing Animals at the command prompt.  I would like to have similar
functionality in my package.  Would someone provide some hints as to what
I need to do (read about xxx...or provide a line of code) so that the data
in the package can be accessed once it is loaded without typing data(foo)
all the time.  Currently, when I type the name of a function it shows the
code for the function.  I would like it to also show the data when I type
the name of any of the data sets.  Thanks for the pointers in advance.

Look at `Writing R Extensions' and the description of the DESCRIPTION 
file, specifically `LazyData'.

That is the manual about packages ....
