delpts_tracked_period_wt {WaverideR}

Remove tracking points which were tracked in a wavelet spectra

Description

Interactively select points for deletion With the track_period_wavelet function it is possible to track points in a wavelet spectra, however errors can be made and as such it is possible to delete these points with the delpts_tracked_period_wt function. This function allows one to select points for deletion. #'

Usage

delpts_tracked_period_wt(
  tracking_pts = NULL,
  wavelet = NULL,
  n.levels = 100,
  periodlab = "Period (metres)",
  x_lab = "depth (metres)",
  palette_name = "rainbow",
  color_brewer = "grDevices"
)

Arguments

tracking_pts

Points tracked using the track_period_wavelet function.

wavelet

Wavelet object created using the analyze_wavelet function.

n.levels

Number of color levels Default=100.

periodlab

label for the y-axis Default="Period (metres)".

x_lab

label for the x-axis Default="depth (metres)".

palette_name

Name of the color palette which is used for plotting. The color palettes than can be chosen depends on which the R package is specified in the color_brewer parameter. The included R packages from which palettes can be chosen from are; the 'RColorBrewer', 'grDevices', 'ColorRamps' and 'Viridis' R packages. There are many options to choose from so please read the documentation of these packages Default=rainbow. The R package 'viridis' has the color palette options: “magma”, “plasma”, “inferno”, “viridis”, “mako”, and “rocket” and “turbo” To see the color palette options of the The R pacakge 'RColorBrewer' run the RColorBrewer::brewer.pal.info() function The R package 'colorRamps' has the color palette options:"blue2green", "blue2green2red", "blue2red", "blue2yellow", "colorRamps", "cyan2yellow", "green2red", "magenta2green", "matlab.like", "matlab.like2" and "ygobb" The R package 'grDevices' has the built in palette options:"rainbow", "heat.colors", "terrain.colors","topo.colors" and "cm.colors" To see even more color palette options of the The R pacakge 'grDevices' run the grDevices::hcl.pals() function

color_brewer

Name of the R package from which the color palette is chosen from. The included R packages from which palettes can be chosen are; the RColorBrewer, grDevices, ColorRamps and Viridis R packages. There are many options to choose from so please read the documentation of these packages. "Default=grDevices

Value

The results of the deletion of the tracking points is a matrix with 3 columns. The first column is depth/time The second column is the period of the tracked cycle The third column is the sedimentation rate based on the duration (in time) of the tracked cycle
