[R] apply and functions with many arguments
Dear all, I would like to use the following function fitdist(data, distr, method=c(mle, mme, qme, mge), start=NULL, fix.arg=NULL, ...) for many different distr values like distr=c(norm,lnorm,pois) (just a small example) and take back into a list the parameter name which is what is inside distr plus what the function fitdist returns (another list). How can I do that ?

Re: [R] apply and functions with many arguments
Hello Paul
I have also tried this one
distrList-c(norm,lnorm,pois,exp,gamma,nbinom,geom,logis);
return (lapply(distrList, function(distrList) { fitdist(x1,distrList)}));
which seems to work.
I am not sure though if there is a strict performance penalty.
B.R
Alex

Hi,
Take a look at 'expand.grid' and 'ddply' from the plyr package or
foreach from the foreach package.
cheers,
Paul
