In addition to seeing the code by typing the name of the function
(and copying it from there into a file), you can also enter
debug(fitdistr), for example. Then the next time you use fitdistr,
either directly or indirectly, it puts you in the environment of that
function, and you can

mydt - function(x, m, s, df) dt((x-m)/s, df)/s
Hi,
I was wondering if anyone could tell me how m and s are calculated for a t
distribution?
I thought m was the sample mean and s the standard deviation- but obviously
I'm wrong as this doesn'y give the same answer.
Thank you
