Description

Creates different alpha values along a vector

Usage

alphaAlong(x, head = 20, skew = -2)

Arguments

x	Vector along which alpha is created
head	Numeric parameter influencing the lenght of the head
skew	Numeric parameter influencing the skew of alpha

Value

Numeric verctor with different alpha values

Examples

library(ggplot2)
d = data.frame(x = 1:100, y = 1:100, a = alphaAlong(1:100, head = 20, skew = -2))
bm = ggplot(d, aes(x, y))
bm + geom_path(size = 10)
bm + geom_path(size = 10, alpha = d$a, lineend = 'round')
