Create the list of colors for the LDATS summary plot

Source: R/LDA_TS_plots.R

A default list generator function that produces the options for the colors controlling the panels of the LDATS summary plots, needed because the change point histogram panel should be in a different color scheme than the LDA and fitted time series model panels, which should be in a matching color scheme. See set_LDA_plot_colors, set_TS_summary_plot_cols, set_gamma_colors, and set_rho_hist_colors for specific details on usage.

set_LDA_TS_plot_cols(rho_cols = NULL, rho_option = "D",
  rho_alpha = 0.4, gamma_cols = NULL, gamma_option = "C",
  gamma_alpha = 0.8)

Arguments

rho_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).
rho_option

A character string indicating the color option from viridis to use if `rho_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").
rho_alpha

Numeric value [0,1] that indicates the transparency of the colors used. Supported only on some devices, see rgb.
gamma_cols

Colors to be used to plot the LDA topic proportions, time series of observed topic proportions, and time series of fitted topic proportions. Any valid color values (e.g., see colors, rgb) can be input as with a standard plot. The default (gamma_cols = NULL) triggers use of viridis color options (see gamma_option).
gamma_option

A character string indicating the color option from viridis to use if gamma_cols == NULL`. Four options are available: "magma" (or "A"), "inferno" (or "B"), "plasma" (or "C", the default option), "viridis" (or "D") and "cividis" (or "E").
gamma_alpha

Numeric value [0,1] that indicates the transparency of the colors used. Supported only on some devices, see rgb.

Value

list of elements used to define the colors for the two panels of the summary plot, as generated simply using set_LDA_TS_plot_cols. cols has two elements: LDA and TS, each corresponding the set of plots for its stage in the full model. LDA contains entries cols and options (see set_LDA_plot_colors). TS contains two entries, rho and gamma, each corresponding to the related panel, and each containing default values for entries named cols, option, and alpha (see set_TS_summary_plot_cols, set_gamma_colors, and set_rho_hist_colors).
