I am new to R enviorns & greatly recommend the Venables Ripley "Modern Applied stats with S". I am interested in a sampling say 5 day continuous windows of stock returns from a population and not applying a function to it. Is this avaiable in the 'boot' or the 'sample' function, and if it is, how? I have been able to sample single days returns, but not multiple continuous days. Thank you in advance, Sri Viswanath Senior Portfolio Manager Welton Investment Corporation
