Hello, I'm having some trouble getting things to look as I want with filled.contour.
1. My first issue is that I am unable to add line segments to my plot where I want them. Using the rug pattern example: x <- y <- seq(-4*pi, 4*pi, len = 27); r <- sqrt(outer(x^2, y^2, "+")); filled.contour(cos(r^2)*exp(-r/(2*pi))); segments(0.2,0.2,1,0.2); The line segment is not found in relation to the x-axis but is seemingly squished over by the color bar. If I try to achieve the line this way: filled.contour(cos(r^2)*exp(-r/(2*pi)),plot.axes={lines(c(0.2,1),c(0.2,0.2))}) Now when I add the axis back it is misaligned. axis(1). 2. Secondly I'm finding the literature difficult to understand on how to make a nice color scheme. Below is a nice scheme I found from an example, except I don't understand why the scale seems to cycle into blue again for larger values, even though I think I am setting the number of levels of colors and contour levels to be equal. Basically I want reds for the highest values and blues for the lowest: filled.contour(cos(r^2)*exp(-r/(2*pi)),nlevels=25,col=hsv(h=seq(from=.7,to=0,length=25))) 3. I'm used to working with matlab where it was simple to make the color scale the same on multiple figures using caxis(). However I don't see this option for filled.contour (possibly it exists for levelplot() but I was having even less success understanding that one). I only see the option to set the number of levels which doesn't really accomplish what I want for plots that are going to have widely varying limits. Thanks very much for any help, John.
