Wee Haa!
I hit a nerve there.
My inbox was awash with responses. Was it because it was easy or an issue?
I knew it would be an issue (sensitive to anomalous values) but was keen to
see the obvious.
I won't cover all answers or I'll be here for the evening.
The bottom (easiest) line is use filter(), running.ave seems to be
temperamental, I assume it had something to do with NA's but didn't pursue
it...
David Smith:
"Running means is easy to do with the function "filter". For example:
filter(x,rep(1,3)/3)
does running means with a window size of 3."

unacceptable in the eyes of some?
Thanks
