[R] Exclude 2014 data from mean

[Bert Gunter]

This is very basic. Have you made **any** effort to learn R -- e.g. by
going through an R tutorial? If not, please do this before posting
further. This will save you -- and foks on this list, probably -- a
lot of grief in the long (or even short) run.

Also, if/when you do post further, post in plain text, not HTML, as
requested by the posting guide below.

Cheers,
Bert
