Hey, "be careful you are insulting" (;-) R core code would *never* contain
stupid silly code
such as <logical> == TRUE
> fortunes :: fortune("TRUE.*TRUE", fixed=FALSE)
Ted Harding: But you can also do these with 'any' and 'all', e.g. any(v==TRUE).
Thomas Lumley: or any( (v==TRUE)==TRUE), or any( ((v==TRUE)==TRUE)==TRUE)...
Or, perhaps, any(v). Lewis Carroll wrote a nice piece
on this theme.
-- Ted Harding and Thomas Lumley (about implementing an 'or' of a logical
vector)
R-help (August 2004)
It uses if(isTRUE(na.rm))
and yes,
people using T for TRUE are "selber tschuld" (Swiss German for "your fault!")
