All,
I have a function to split a fixed rate bond into a floater/inverse floater
combination (something typically done in mortgage securtizations). The
function returns a list which serves as the deal structure over which principal
payment rules will iterate. However, I would like to call the

My package is S4 an I would like to strongly type the input to the constructor

customize the call to new or when the inputs are differen

My package has 5 directories which serve as data folders. I created source

create and store the objects as this makes it easier to add more bonds to the
