All,
I am creating a mortgage prepayment model package. The idea is to create a
class FRMModelFunction and each slot in the class is a function that may be use
in the prepayment. So I would like to create a generic and method that will
allow me to call the slot by name. However, I think that I am missing
something in my setup
If I run the below code I can do the following
Omega(Model) which returns the function
Omega <- Omega(Model) which then assigns the function and allows me to pass
values and get a result from Omega(x = 1)
However I can also get a result by directly accessing the slot
Model@Omega(x=1)
What I want to do is set a generic and method so that I can do the following
Omega(x=1)
The below is close but still not what I would like to have. Is what I have
described possible and if so what have I missed?
Glenn
setGeneric("Omega", function(object,...) {standardGeneric("Omega")})
setMethod("Omega", signature = "FRMModelFunction",
definition = function(object){object@Omega})
setClass("FRMModelFunction",
representation(
Omega = "function"))
Model <- new("FRMModelFunction",
Omega = function(x = numeric()) {return(max(0, min(1, x)))}
)
