Alternative color palette for black-and-white graphs (for printing purposes).
Source:R/init_pal.R
pal_bwp.Rdpal_bwp is initialized to a vector of named elements (colors)
to define a strict (black-and-white, b/w) scenario color scheme
that is suited for printing graphs in black-and-white.
Details
pal_bwp is a stricter version of the greyscale
palette pal_bw that enforces
black text and lines on white boxes. Thus, the bounds of frequency boxes
are invisible on white backgrounds unless the default of
f_lwd = 0 is changed (e.g., to f_lwd = 1).
Some background colors (of frequencies) are also used as
foreground colors (of probabilities, e.g.,
in plot_curve and plot_plane).
For this reason, the plotting functions detect and
adjust colors and/or line settings when pal_bwp
is used.
See pal_bw for a more permissible black-and-white
palette that uses various shades of grey for frequency boxes
so that their bounds remain visible on a white background
when f_lwd = 0 (as per default for most graphs).
See pal for default color information.
Assign pal <- pal_bwp to use as default color scheme
throughout the riskyr package.
