[R] R commands

[Chou Andy]

I'm a R beginner.  Recently I conduct a project about expected return that 
involves using R for calculations.  I encounter three questions as follow:

Q1.  How to use R to demonstrate bootstrapping and Monte Carlo simulation 
under 10,000 times of random selection?
Q2.  How to do a loop in R?
Q3.  How to use R to do binominal tree calculation under multiple periods?

I'm perplexed by the R commands, so any hints or examples will be highly 
appreciated.
