Simplifying particular piece of code
...uot;ETM.AV120",
stdev="ETM.SD120"))
Is there a way to simplify this, some sort of loop?
mrets is a zoo object.
.AV120 and .SD120 are columns in this object.
I need the exact .SR column names.
This does not work:
SRnames <- paste(colnames.mrets, ".SR", sep="")
AVnames <- paste(colnames.mrets, ".AV120", sep="")
SDnames <- paste(colnames.mrets, ".SD120", sep="")
for(i in seq(SRnames)){
mrets <- merge(mrets, SRnames[i]=apply(mrets, 1, MyFunc,
ret=AVnames[i], stdev=SDnames[i]))
}
Help much appreciated.
Regards,
Se...
