tCol: Create colors with transparency

In aspillaga/fishtrack3d: Analysis of Passive Acoustic Telemetry Data in 3D

Description

This function easily creates transparent colors providing a color name and the desired proportion of transparency

Usage

tCol(color, trans = 50, name = NULL)

Arguments

color	character vector with the names or codes of the original colors.
trans	percentage of transparency to apply to the colors (0 to 100). If a unique value is provided, the same percentage of transparency will be applied to all the colors. If it is a vector of the same length as color, a given transparency will be applied to each color.
name	optional name to give to the resulting colors.

Examples

plot(rnorm(1:100), rnorm(1:100), pch = 16, cex = 2, col = tCol("black", 70))
points(rnorm(1:100), rnorm(1:100), pch = 16, cex = 2, col = tCol("red", 40))
points(rnorm(1:100), rnorm(1:100), pch = 16, cex = 2, col = tCol("blue", 60))
