set_rho_hist_colors: Prepare the colors to be used in the change point histogram

In weecology/LDATS: Latent Dirichlet Allocation Coupled with Time Series Analyses

Description

Based on the inputs, create the set of colors to be used in the change point histogram.

Usage

set_rho_hist_colors(x = NULL, cols = NULL, option = "D", alpha = 1)

Arguments

x	matrix of change point locations (element rhos) from an object of class TS_fit, fit by TS.
cols	Colors to be used to plot the histograms of change points. Any valid color values (e.g., see colors, rgb) can be input as with a standard plot. The default (rho_cols = NULL) triggers use of viridis color options (see rho_option).
option	A character string indicating the color option from viridis to use if "cols == NULL". Four options are available: "magma" (or "A"), "inferno" (or "B"), "plasma" (or "C"), "viridis" (or "D", the default option) and "cividis" (or "E").
alpha	Numeric value [0,1] that indicates the transparency of the colors used. Supported only on some devices, see rgb.

Value

Vector of character hex codes indicating colors to use.

Examples

  data(rodents)
  document_term_table <- rodents$document_term_table
  document_covariate_table <- rodents$document_covariate_table
  LDA_models <- LDA_set(document_term_table, topics = 2)[[1]]
  data <- document_covariate_table
  data$gamma <- LDA_models@gamma
  weights <- document_weights(document_term_table)
  TSmod <- TS(data, gamma ~ 1, nchangepoints = 1, "newmoon", weights)
  set_rho_hist_colors(TSmod$rhos)
