Agreed, nobody has deemed it "default", but is there any other such package
that you can think of for this purpose.
Not that I know. Suggesting it is perfect. I'd just not call any package
a "default" if it does not ship with R.

What have you tried so far - can you explain? "fitdistrplus" package is the
default package for fitting distributions.
It is a contributed packages, and perhaps it is a good one (I do not
know), but calling it the *default* ... who defined that?

Subject: [R] Negative exponential fit
We need help....
We are doing a project for a statistical class in and we are looking at
world record times in different running events over time. We are trying to
fit the data with a negative exponential but we just cant seem to get a
function that works properly.
we have on our x-axis the date and on the y-axis the time(in seconds). So as
you can imagine, the times have decreased and appear to be approaching a
limit. Any ideas for a nls function that would work for us would be greatly
appreciated.
