lapply in R, same function different arguments

Question

I have two fit objects reg and reg1.

I want to run summary() on each without having to re specify whole thing, just the arguments. What is an easy way to do this in general in R? I tried something like this:

lapply(c(reg, reg1), function(x) summary.default(x))

but note that

> class(reg1)
[1] "glm" "lm" 
> class(reg)
[1] "lm"

regardless of the general solution asked for, is it the different classes that are messing with this particular case? is it the format of the first lapply arg.?

Edit: Figured it out

lapply(list(reg, reg1), summary)

but why does it need to be list()? I see that list(reg) calls lm. why is c(reg, reg1) not an appropriate way to pass arguments?

Thanks
