[R] searching help for partial matches

[Steve Jaffe]

help.search -- excellent

I'm a bit confused though -- doc seems to say that ??pattern is same as
help.search(pattern) but it doesn't work that way for me...I'd been trying
?? for some time without success. 

For example,
??allequal #returns
No documentation for '?allequal' in specified packages and libraries:
you could try '???allequal'

It looks like it is treating "?allequal" as the input to the ? function...
Any idea what I need to get this work correctly?

Thanks

?help.search
help.search("allequal")
help.search(apropos="allequal")
??allequal
