looks like filled.contour function has been updated or something, and now it automatically adds a white grid inside the plot (inside filled contour plot area), but I don't know how to remove it.
i will give a little example:
x <- 1:12
y <- 1:12
xvals <- c(2,4,7,10,14,21,30,60,90,120,180,365)
fx <- as.numeric(as.factor(xvals))
filled.contour(fx, y, outer(x,y),
axis(2) ## plain
As you can see the second plot (plot now), has a white grid in it, how do I get rid of that grid?
Thanks, Ricardo Faria.
