[R] Non-alignment of <NA> in rownames

Hello everyone,

Apologies in advance if you have received this multiple times!

On a thread similar to that posted by Don MacQueen
(http://www.r-project.org/nocvs/mail/r-help/2002/3455.html): is there any
way to nicely format NA's when listed as rownames?  When NA's are part of
rownames, the alignment is thrown off:

> z <- matrix(c(100, 200, 300))
> z
[1,]  100
[2,]  200
[3,]  300
> rownames(z) <- c("x", "y", NA)
> z
x     100
y     200
<NA>    300

This strikes me as strange, especially because the brackets don't affect NA
alignment elsewhere (like as an element in a dataframe or matrix).  Any
