Re: [R] how to extract options for a function call

Try this: For optim: eval(formals(optim)$method) For dist function: eval(body(dist)[[3]][[3]]) On Mon, Apr 18, 2011 at 10:56 AM, fisken wrote: > Hi, I'm having some difficulties formulating this question. > > But what I want, > is to extract the options associated with a parameter for a functi

[R] how to extract options for a function call

Hi, I'm having some difficulties formulating this question. But what I want, is to extract the options associated with a parameter for a function. e.g. method = c("Nelder-Mead", "BFGS", "CG", "L-BFGS-B", "SANN") in the optim function. So I would like to have a vector with c("Nelder-Mead", "BFGS"
