Or not used delay() at all. That code looks a bit warped.
AFAICT, you could have 'from' defaulting to lims[1] and 'to' to
lims[2], then in the body let
if(missing(from) || missing(to))
lims <- if(missing(xlim))
if (par("xlog"))
10 ^ par("usr")[1:2]
else
par("usr")[1:2]
else
xlim
and get the same result (notwithstanding that you probably don't want
to use par("usr") in that way)
