In RIbench: Benchmark Suite for Indirect Methods for RI Estimation
as.rgb R Documentation
Convert color-names or RGB-code to possibly semi-transparent RGB-code.
Description
Function takes the name of a color and converts it into the rgb space. Parameter "alpha" allows
to specify the transparency within [0,1], 0 meaning completey transparent and 1 meaning completey
opaque. If an RGB-code is provided and alpha != 1, the RGB-code of the transparency adapted color
will be returned.
Usage
as.rgb(col = "black", alpha = 1)
Arguments
col
(character) name of the color to be converted/transformed into RGB-space (code). Only
those colors can be used which are part of the set returned by function colors(). Defaults
to "black".
alpha
(numeric) value specifying the transparency to be used, 0 = completely transparent,
1 = opaque.
Value
RGB-code
