...y wide range of meanings, but they are all conceptually similar. I've looked in a couple of the classic R texts, the extensions and developers' manuals, and R help archives, and didn't find a definition. Of course, I may have missed it. Thanks in advance.

grDevices::convertColor has arguments 'from' and 'to' which can take on value 'XYZ'. Can someone confirm that 'XYZ' is the same as the CIE chromaticity coordinates that are also sometimes refered to as 'xyY' in the literature? Or are these the CIE tristimulus values? It looks to me like the first case is true, but I would appreciate hearing from one of

Gurus: I keep seeing other people?s code that contain ideas like If (x == 2L) X[-1L] X - 1L I have some idea of what?s going on, but where is the use of concepts like ?2L? documented?

A new package 'nnls' is now available on CRAN. The package provides an R interface to the Lawson-Hanson NNLS algorithm for non-negative least squares that solves the least squares problem A x = b with the constraint x >= 0.

Still playing with Lattice... I want to use panel.text(x, y etc) but with x and y in plot coordinates (0,1), not user coordinates. I think if I had this problem with traditional graphics, I could use grconvertX to make the change. I did come across convertX {grid} but this doesn't seem to be what I need. Is there a function like grconvertX in Lattice, or is there a flag or some other
