[R] Error message in SIS package

[Jeff Newmiller]

I doubt I will know how to help you in any case, but I can see that you are shackling yourself to a very small (possibly empty) set of helpers by not making your example reproducible. 

You will also slow any helpers down once you change that if you post again in HTML format... set your email program to send plain text so the code you supply doesn't get corrupted.
