Hi
I am trying to define a function fu() in the following way but when I try to
run I get the error that ma1 is not found. I am not sure where I am going
wrong? Does the scope of ma1 not extend to an expr.frame object?
expr.frame() is under library tradesys.
function (y,ma1,ma2)
{
x <- y[, c("Open","Close")]
d <- expr.frame(x, list(MAf=quote(SMA(Close, ma1)), MAs=quote(SMA(Close,
ma2))))
}
>fu(spx,60,120)
Error in runSum(x, n) : object 'ma1' not found
Thanks for your kind help.
