Dear R community
I try to create a new operator to build a special sum of two CashFlows. (my
S4 Class)
I tried the following but this is actually not what I want.
setGeneric("++",function(e1,e2)standardGeneric("++"))
setMethod("+",signature=list("CashFlow","CashFlow"),function(e1,e2){
print("+")
})
setMethod("++",signature=list("CashFlow","CashFlow"),function(e1,e2){
print("++")
})
The problem here is that this work but it treats "++" as a general
function.. the call is "++"(e1,e2).
I'm looking for somthing like e3 <- e1 ++ e2
Thanks a lot for your help.
Best regards,
Roger
