[R-sig-Geo] Adding maps to a filled contour plot

[Anne Hertel]

Hi,

I am trying to plot a filled contour map and overlay it with a map, but I'm having trouble with the map. The map is plotted, but it is stretched out over the color bar, and doesn't stay within the plotting area. If I just use the 'contour' function the 'map' function works fine, but I want the contours filled in.

Here's the code:
filled.contour(cor.enso.map, x=seq(-126.5625,-64.6875,,23),y=seq(23.720175,51.625732,,11),xlab='longitude',ylab='latitude')
map(xlim=c(-127,-65),ylim=c(23,52),add=T)

where cor.enso.map is a matrix of size [23,11].

How do I make the map stay within the plotting area?

Thanks,
Anne Hertel
