Rainflow, range pair counting
A quick Google search suggests that the methods are used in material fatigue studies where varying stress loads are placed upon the material, which puts this into a materials engineering context. Using rseek.org does not give any joy. Perhaps someone with experience in that domain will chime in. Regards, Marc Schwartz

R is used by many many folks, and most of us don't have the domain knowledge to make heads or tails of what you're mentioning here. You'll need to greatly clarify and perhaps ask on the appropriate R-SIG-* list. (Ecology maybe?) Perhaps rseek.org is also of help.

Hello I got some question about R. Im searching for a function or R-code which makes me some collectives. In the literature they are called:
level crossing counting
rainflow counting
range pair counting
Cant believe that?s not available for R. May I just looking for the wrong word. There functions are used to count the cycles (Range and Means) of a time serie. Thx for helping :)
