R help - Mar 2006 - lattice-Internal

Hi,

The functions prepanel.default.bwplot() and lpretty() are not running in
Deepayan's
barley example concerning vertical bars with the lattice function barchart().
Why, is there a restricted use for the package lattice-Internal?

Hi Urs,
Are you referring to the ?barley help topic example that calls dotplot() ?.
I just tried it via example(barley) and cut-and-paste it and it ran with now
complaints on my system:

R 2.2.1, Windows 2000 SP4, lattice version 0.12-11 

Both the functions you mention seem to be there:
> getAnywhere("lpretty")
A single object matching 'lpretty' was found
It was found in the following places
  namespace:lattice

...
> getAnywhere("prepanel.default.bwplot")
A single object matching 'prepanel.default.bwplot' was found
It was found in the following places
  namespace:lattice

...

I don't know what "lattice-Internal" is: by its core nature R does
not
restrict anything.

Could you perhaps tell us what versions you are using? Some more specifics
(see http://www.r-project.org/posting-guide.html ) will increase r-help's
ability to solve your problem.

What example? Please be more specific.

prepanel.default.bwplot() and lpretty() have always been meant for
internal use only. In the pre-namespace days, they were documented in
lattice-internal.Rd, and after the advent of namespaces (which was
years ago) they were unexported (and undocumented). In other words,
you should not be using them.
