See the description of
options("warn") for the circumstances under which there is a
last.warning object and
warnings() is used. In essence this is if
options(warn = 0) and
warning has been called at least once.
It is possible that
last.warning refers to the last recorded warning and not to the last warning, for example if
options(warn) has been changed or if a catastrophic error occurred.
It is undocumented where
last.warning is stored nor that it is visible, and this is subject to change. Prior to R 2.4.0 it was stored in the workspace, but no longer.
