remove doc for defunct functions
defunct ani.start() and ani.stop()
try hard to make code width < 90; dear R core, that is nonsense!
mark ani.start() and ani.stop() as internal
a util function to execute code in a dir
my attempt to fix #31 by removing outdir from ani.options(); also closes #32
roxygenize
explicitly export functions that were designed to be visible
roxygenize; removed keywords, which are not super useful in Rd
cosmetic
use @family instead of writing @seealso repeatedly
roxygenize
re-wrap comments
no longer mention ani.start()/ani.stop()
no need to specify utils; R will find that
cosmetic
remove outdir in saveHTML() (#31)
remove the so-called tests, since they are not used at all
add a new argument to saveHTML() to conveniently remove the navigator
tests for remove_navigator()
