 localScoreC_double R Documentation

## Local score for sequences of floating values

### Description

Calculates the local score for a sequence of doubles. Only provides the first occurrence. Use function suboptimalSegment() or Lindley() to obtain the others localizations of the different realizations of the local score.

### Usage

```localScoreC_double(v, supressWarnings = FALSE)
```

### Arguments

 `v` A sequence of values as vector. `supressWarnings` if warnings should be displayed

### Value

A structure containing: the local score value and the begin and end index of the segment realizing this optimal score ; all the local maxima of the Lindley process (non negative excursion) and their begin and ens index ; the record times of the Lindley process but only the ones corresponding to the begin index of non negative excursions

### Examples

```localScoreC_double(c(1.2,-2.1,3.5,1.7,-1.1,2.3))
seq.TwoSegments=c(1.2,-2.1,3.5,1.7,2,-2,-2,-3.5,1,3.5,1.7,1,-2,-2)
# two segments realizing the local score value
localScoreC(seq.TwoSegments)
# only the first realization
localScoreC(seq.TwoSegments)\$localScore
# all the realization of the local together with the suboptimal ones
localScoreC(seq.TwoSegments)\$suboptimalSegmentScores
# for small sequences, you can also use lindley() fonction to check if
# several segments achieve the local score
lindley(seq.TwoSegments)
plot(1:length(seq.TwoSegments),lindley(seq.TwoSegments),type='b')
seq.TwoSegments.InSameExcursion=c(1,-2,3,2,-1,0,1,-2,-2)
localScoreC(seq.TwoSegments.InSameExcursion)
# lindley() shows two realizations in the same excursion (no 0 value between the two LS values)
lindley(seq.TwoSegments.InSameExcursion)
plot(1:length(seq.TwoSegments.InSameExcursion),lindley(seq.TwoSegments.InSameExcursion),type='b')
# same beginning index but two possible ending indexes
# only one excursion realizes the local score even in there is two possible length of segment
localScoreC(seq.TwoSegments.InSameExcursion)\$suboptimalSegmentScores
```
