Set theiler window on a distance matrix or recurrence matrix.
setTheiler(RM, theiler = NA, silent = FALSE, chromatic = FALSE)A distance matrix (set emRad = NA to estimate a radius), or a matrix of zeroes and ones
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.
Silent-ish mode
Perform a chromatic RQA. This assumes the recurring values represent the labels of an unordered categorical variable (default = FALSE)
The matrix with the diagonals indicated in the theiler argument set to either max(RM)+1 (if RM is a distance matrix) or 0 (if RM is a recurrence matrix).
