Now how did this not come up in a search: perhaps because of the way you
spell optimization? I have
No help files found with name or title matching `optimisation'
Help files with name or title matching `optimization':
partition(multiv) Partitioning by Iterative Optimization
lmeScale(nlme) Scale for lme Optimization
portfolio.optim(tseries) Portfolio Optimization
optim(base) General-purpose Optimization
optimize(base) One Dimensional Optimization
which shows we probably need to find a way to check variant spellings.
(BTW: just in case anyone tells me the British spell with an `ise', the
Oxford English Dictionary does not.)
