Hi everyone,
How do I draw a transparent ploygon overlaying with a scatter plot?
Let's say, we call plot() to have a scatter plot, then call polygon() to
add a polygon. I was hoping the polygon can be transparent so the scatter
plot is still visible. I can't find any argument in polygon() for
The standard colors in R are opaque, but you can add an alpha value to make
them semi-transparent. In this example we set alpha halfway between 0 and 255
to define a semi-transparent red:
set.seed(42)
x - runif(10)*10
y - runif(10)*10
plot(x, y, pch=16)
col2rgb(red, alpha=TRUE)
[,1]
You can use adjustcolor() to do some of the arithmetic for you. E.g.,
the following draws red squares with 10 opacities ('alpha's) from 5%
to 95%:
plot(1:10)
square - 0.45 * cbind(c(-1,1,1,-1),c(-1,-1,1,1))
for(i in 1:10) polygon(square+i, col=adjustcolor(red, alpha=(i-.5)/10))
