Make single vector gray-gradient
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
transpGraySca(startGray = 0.2, endGrey = 0.8, nSteps = 5, transp = 0.3)
startGray |
(numeric) gray shade at start |
endGrey |
(numeric) gray shade at end |
nSteps |
(integer) number of levels |
transp |
(numeric) transparency alpha |
character vector (of same length as x) with color encoding
layout(1:2) col1 <- wrMisc::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")
