Get (C)RQA measures from a Recurrence Matrix

Use rp_measures

Usage

rp_measures_main(
  RM,
  emRad = NULL,
  DLmin = 2,
  VLmin = 2,
  HLmin = 2,
  DLmax = length(Matrix::diag(RM)),
  VLmax = length(Matrix::diag(RM)),
  HLmax = length(Matrix::diag(RM)),
  AUTO = NULL,
  theiler = NULL,
  chromatic = FALSE,
  matrices = FALSE,
  doHalf = FALSE,
  Nboot = NULL,
  CL = 0.95,
  doParallel = FALSE
)

Arguments

RM

A distance matrix (set emRad = NA to estimate a radius), or a matrix of zeroes and ones

emRad

Threshold for distance value that counts as a recurrence (ignored is RM is a binary matrix)

DLmin

Minimal diagonal line length (default = 2)

VLmin

Minimal vertical line length (default = 2)

HLmin

Minimal horizontal line length (default = 2)

DLmax

Maximal diagonal line length (default = length of diagonal -1)

VLmax

Maximal vertical line length (default = length of diagonal -1)

HLmax

Maximal horizontal line length (default = length of diagonal -1)

AUTO

Auto-recurrence? (default = FALSE)

theiler

Use a theiler window around the main diagonal (Line of Identity/Synchronisation) to remove auto-correlations at short time-lags:

0 will include the main diagonal in all RQA measure calculations.
1 will remove the main diagonal from all RQA measure calculations.
NA (default), will check if the matrix is symmetrical , if so, it will remove the diagonal by setting theiler = 1 (Line of Identity, Auto-RQA), if it is not symmetrical (Line of Synchronisation, Cross-RQA) it will set theiler = 0.
A value greater than 1 will remove that many diagonals around and including the diagonal from all RQA measure calculations. So theiler = 2 means exclude 2 diagonals around the main diagonal, including the main diagonal itself: [-1,0,1]. If theiler is a numeric vector of length(theiler) == 2 it is possible to exclude an asymmetrical window. The values are interpreted as end points in a sequence of diagonal ID's, e.g. theiler = c(-1,5) will exclude [-1,0,1,2,3,4,5]. If length(theiler) > 2, the values will be considered individual diagonal ID's, e.g. theiler = c(-3,-1,0,2,5), will exclude only those specific ID's. Also see the note.

chromatic

Force chromatic RQA? If NA the value of the RM attribute "chromatic" will be used, if present (default = NA)

matrices

Return matrices? (default = FALSE)

Nboot

How many bootstrap replications? (default = NULL)

CL

Confidence limit for bootstrap results (default = .95)
