Code works on Mac but not Windows

Hello All,

Testing my code on a Windows based machine today. ?There seems to be an offending line of code. ?I have pasted it below. ?Basically, I check to see if the user passed a fit method to TermStructure and if not then default to "ns". ?

The above works fine on my Mac but a windows build errors no method. ?I have to pass a method = "ns" in the function. ?If I pass the value for method to the function it will run with no error. ?Any thoughts are appreciated.

Best Regards,
Glenn

? #Default method for TermStructure
? if(missing(method)) method = "ns"
