R help - Jul 2010 - pass list of args to function call

I was wondering how i can get a list of arguments to evaluate within function
call.  I'd like to be able do something like this:


#mod <- glm(y~1,data=df,family="binomial")

opt <- list(family="binomial")
mod <- glm(y~1,data=df,opt)


Any idea how this can be done properly?  TIA

Try this:

 do.call(glm, list(y ~ 1, data = df, family = 'binomial'))

Thanks for your helpful response.

I have a related question, i would like to further generalize the function
by having the call arg of do.call function being referenced.  Like this:


model.fun <- glm
model.opt <- list(y1~1,data=df,family="binomial")
rslt <- do.call(model.fun,model.opt)


This works but the model.fun object shows the code for glm.  This is
cumbersome in output, is there anyway to avoid this by having the model.fun
be a reference/pointer to the glm function?

TIA
