Checking for replies, I see that I was imprecise in my original posting.

I meant: "I am interested in obtaining, for each subject, the latest timepoint when A SUBJECT HAD HAD UNINTERRUPTED C4NAIVC and CD4MEMC VALUES available."

In other words, I want to ignore any values after a missing timepoint, and consider LatestNaive the maximum of week1 before any missing C4NAIVC or CD4MEMC.

Sorry for my clumsy formulation of the question.
