Thank you for your efforts.
Although it is still not working, it feels like getting closer and
closer.
id cycle1 cycle2 cycle3
1 1 cmf cmf cmf
2 2 mfc mfc mfc
3 3 acfNA acfNA NAcfm
I really appreciate transformation from subsets ("c","m","f") to "cmf".
That was critical for me.
Hopefully, I'll figure out the rest later with ddply from plyr package.
At least this is my idea for now.
