[Rd] Proposals

We just launched the Epi-package for R.

It contains some functions which are not particular to epidemiology, and which you may consider moving to base/stats/graphics.

They are:

nice() - an extension for pretty() with some improved control for

            log-axes.
Relevel() - extension of relevel() allowing collapsing oflevels and

            arbitrary reshuffling of ordering ncut() - a cut function returning a numerical rather than factor object.

If you take some of them over, I'll remove them from Epi, and make the necessary changes should the names be changed.

As a quite separate matter, I often find myself doing:

AAnam <- [some named list]
AA <- array( NA, dim=sapply( AAnam, length ), dimnames=AAnam )

It would be a nice facility to have dim= default to sapply( dimnames, length ) if dimnames were given as argument. There really is no other reasonable value possible for dim if dimnames are given.

Best,
Bendix
