Passing function arguments to dataset names
...wondering if anybody knows the answer. I am a relatively new R user. How do I use an argument of a custom function in the name of a dataset in R? For example, I have the function: MyF <- function(Tic, price){ xxxxx xxxxx xxxxx Ratio.Tic<- SharpeRatio.annualized(roc) } I would like to have a dataset that's labelled Ratio.MSFT, Ratio.XOM, Ratio.IBM...etc. The objective is to append multiple Ratio.Tic datasets that contains all the ratios in one single data. Thanks in for your time! Mateo -- View this message in context: http://r.789695.n4....
