[BioC] function log.na() removed from package vsn >= 1.5.1

[Wolfgang Huber]

Hi all,

as a small step towards removing some clutter and redundancy, the
functions "log.na" and "sqr" have been removed from the vsn package,
development version (1.5.1).

The log.na function (and many other similar ones) can still be found in
the marray package. It simply provides a version of the log function that
does not throw warnings when called with non-positive arguments:
log.na = function (x, ...) log(ifelse(x > 0, x, NA), ...)

Best wishes
 Wolfgang
