[R] using lapply

I have a function with the follow signare:

apply.strategy(instr, strat)

where instr and strat are both objects of classes instrument and strategy respectively.

I want to apply this function to a list that holds objects of the class instrument.

Currently I am doing this by explicit looping:

for(i in length(instr.list) ) {

    apply.strategy(instr.list[[i]], my.strat) }

Is it possible to achieve this task by using one of the built in functions in R? I have looked at lapply but can't quite figure out how to pass the arguments.

What would be the performance implications of one method vs. the other?

Thanks,
Kushan
