Hi Mateo, not sure if I totally get what you're after, but maybe this helps:
SharpeRatio.annualized <- function(roc){ print("I'm computing the Sharpe Ratio") return(9999) } MyF <- function(Tic, price){ print("Option 1") expr <- expression(Ratio.Tic <- SharpeRatio.annualized(roc)) print(expr) eval(expr) print(Ratio.Tic) rm(Ratio.Tic) print("Option 2") expr <- paste("Ratio.", quote(Tic), " <- SharpeRatio.annualized(roc)", sep="") print(expr) eval(parse(text=expr)) print(Ratio.Tic) rm(Ratio.Tic) print("Option 3") frmls <- formals("MyF") expr <- sapply(names(frmls), function(x){ expr <- substitute(NAME <- SharpeRatio.annualized(roc), list(NAME=as.name(paste("Ratio", x, sep=".")))) return(expr) }) print(expr) sapply(expr, eval, envir=environment()) print("Ratio.Tic") print(Ratio.Tic) print("Ratio.price") print(Ratio.price) } MyF() Have fun with R!
