HLrainflow: Evaluation of rainflow range and mean values by HLrainflow...

In ShinsukeSakai0321/HL:

Evaluation of rainflow range and mean values by HLrainflow algorithm

Description

HLrainflow algorithm which is exactly same as rain-flow algorithm is applied to the vector of peak values and the combination of half-range and mean values are returned.

Usage

HLrainflow(Peak)

Arguments

Peak

Examples

#ASTM E1049-85(2017) Rainflow Counting Example
pk<-c(-2,1,-3,5,-1,3,-4,4,-2)
HLrainflow(Peak=pk)
#Expected results
  halfR halfM

2     4   1.0
3     3  -0.5
4     4  -1.0
5     8   1.0
6     9   0.5
7     8   0.0
