hsv2col function

Convert HSV matrix to R color

Converts a HSV color matrix to R hex color

hsv2col(hsvValue, ...)

Arguments

• hsvValue: numeric HSV matrix, with rownames c("h","s","v") in any order, and optionally "alpha" rowname for alpha transparency.
• ...: additional arguments are ignored.

Returns

character vector of R colors.

Details

This function augments the grDevices::hsv() function in that it handles output from grDevices::rgb2hsv() or col2hsv(), sufficient to run a series of conversion functions, e.g. hsv2col(col2hsv("red")). This function also maintains alpha transparency, which is not maintained by the grDevices::hsv() function.

Examples

# start with a color vector
# red and blue with partial transparency
colorV <- c("#FF000055", "#00339999");

# confirm the hsv matrix maintains transparency
col2hsv(colorV);

# convert back to the original color
hsv2col(col2hsv(colorV));
