Dear R community! I haven't worked with R before but I found it has some nice abilities to create graphics. I made it to create a filled.contour with the settings I want but unfortunately I don't seem to be able to change colors. Instead of the standard colors, I'd like to get dark gray or black for higher values (instead of pink) and light gray or white for lower values (instead of cyan). A second option I'd like to try is having colors change from green (low values) to red (high values)... but right now it seems like I'm miles away from that.
This is what I have so far: model=function(a, b){+4+0.5*a-0.2*b} x=seq(-10, 10, by = 2) y=seq(0, 100, by = 10) z=outer(x, y, model) contour(x,y,z,nlevels=12) mylevels <- seq(0,10,10) filled.contour(x,y,z, main="Title") But when I try to Change the Color theme like this - filled.contour(x,y,z,levels=mylevels,col=grey(seq(0,1,length=length(mylevels)))) - I just get one white and one black bar. Does anyone of you know a solution? Thanks in advance, you'd help me a lot as I've been working on these few lines for a couple already.
