CRAN check warnings about missing documentation

[Skye Bender-deMoll]

R CMD Check --as-cran gives following warnings

* checking Rd \usage sections ... WARNING
Undocumented arguments in documentation object 'saveHTML2'
  ‘title’ ‘pause’ ‘endPause’ ‘loopmode’ ‘overwrite’ ‘description’
Documented arguments not in \usage in documentation object 'saveHTML2':
  ‘global.opts’ ‘single.opts’

Functions with \usage entries need to have the appropriate \alias
entries, and all their arguments documented.
The \usage entries must correspond to syntactically valid R code.
See chapter ‘Writing R documentation files’ in the ‘Writing R
Extensions’ manual.

looks like oxy docs don't match up with the code

Thanks! No issues with the CRAN version now.
