CreateColorsByVar(df, by, b_pal, r_pal_num, pal, output, display)

Arguments

df	dataframe that contains the variable column
by	column name of variable used to create colors. Creates a palette based on the unique number of factors in the variable and assigned colors based on the 'pal', 'b_pal', or 'r_pal' parameters.
pal	name of color palette funtions (e.g., rainbow, heat.colors, terrain.colors, topo.colors, or cm.colors) used to create colors. This parameter has priority over the other color palette parameters. Default is NULL.
r_pal	Specifc number of 'R_pal' color palette from the PlotKML Package (e.g., 1 = R_pal[[1]]). This parameter has priority over the 'b_pal' parameter for setting the colors. Default is NULL.
b_pal	color palette name from 'RColorBrewer' package, default is "Set1". Automatically adjusts number of colors to match the unique number of factors in the 'by' parameter.
output	logical, whether or not to output colors
plot	logical, whether or not display a color pie plot

Details

Used in other functions. Color palette can either be a typical palette (e.g. rainbow, heat.heat.colors, terrain,colors, ) using the 'pal' parameter or a RColorBrewer palette using the 'r_pal' parameter, or a RColorBrewer palette using the "b_pal" parameter (e.g. "Accent"). The number of colors is always automatically adjusted to match the unique number of factors in the "by" parameter column of the df.
