sapply
Newbie question sorry (have tried the help pages I promise)
I have a dataframe (date,stockprice) say and looking how I might get the
return of: dataframe (difference in days, change in stock price) using
sapply - I require a very simple function and don't really want to go down
the zoo and quant mod route
