Hi,
I'm new to R and S4 classes. I defined a class with two methods (myMethod1 and
myMethod2). I want to call myMethod1 within myMethod2. Why does the code below
not work? The name 'myMethod1' doesn't appear to have meaning inside myMethod2,
even though the two methods belong to the same class.
setClass(Class="SomeClass",
representation=representation(
amount="numeric")
)
setGeneric (name="myMethod1",
def=function(object){standardGeneric("myMethod1")}
)
setMethod(f = "myMethod1",
signature = "SomeClass",
definition=function(object) {print(obj...@amount)}
)
setGeneric(name="myMethod2",
def=function(object){standardGeneric("myMethod2")}
)
setMethod(f = "myMethod2",
signature = "SomeClass",
definition=function(object) {print(myMethod1 * 2)}
)
instance <- new(Class="SomeClass", amount=10)
myMethod1(instance) # prints '10'
myMethod2(instance) # ERROR: is supposed to print '20'
Thank you in advance for your help!
Cheers!!
