Make single vector gray-gradient

Description

This function helps making gray-gradients. Note : The resulting color gradient does not seem linear to the human eye, you may try gray.colors instead

Usage

transpGraySca(startGray = 0.2, endGrey = 0.8, nSteps = 5, transp = 0.3)

Arguments

startGray	(numeric) gray shade at start
endGrey	(numeric) gray shade at end
nSteps	(integer) number of levels
transp	(numeric) transparency alpha

Value

character vector (of same length as x) with color encoding

See Also

gray.colors

Examples

layout(1:2)
col1 <- transpGraySca(0.8,0.3,7,0.9) 
pie(rep(1,length(col1)), col=col1, main="from transpGraySca")
col2 <- gray.colors(7,0.9,0.3,alph=0.9)
pie(rep(1,length(col2)), col=col2, main="from gray.colors")
