These functions are used for defining palettes or colors in the
epicontacts package. They include:
cases_pal(n) spectral(n) char2col(x, pal = cases_pal, NA_col = "lightgrey") transp(col, alpha = 0.5)
An integer indicating the number of colors.
A character or a factor to be converted to colors.
A color palette.
The color to be used for NA values.
A color vector to which transparency should be added.
The threshold to be used for transparency: 0 for full transparency, and 1 for full opacity.
cases_pal: discrete color palette used for cases (comes from the
spectral: continuous color palette (comes from the
transp: makes colors transparent (comes from the
char2col: translates a character or a factor to a color using a
palette (comes from the
barplot(1:5, col = cases_pal(5))barplot(1:50, col = cases_pal(50))
