如何在R中的填充轮廓图中获取轮廓线和轴标签

Question

I have found that I can get either contour lines with incorrect axis labels, or correct axis labels and no contour lines. Here is some code that produces the former:

x<-c(1:10)
y<-c(1:10)
z<-matrix(x,nrow=length(x),ncol=length(y))
filled.contour(z,plot.axes = { contour(z, nlevels = 20, 
                                     drawlabels = T, axes = FALSE, 
                                     frame.plot = FFALSE, add = TRUE);
                 axis(1); axis(2) } )

And here is some that produces the latter:

x<-c(1:10)
y<-c(1:10)
z<-matrix(x,nrow=length(x),ncol=length(y))
filled.contour(x,y,z,plot.axes = { contour(z, nlevels = 20, 
                                     drawlabels = T, axes = FALSE, 
                                     frame.plot = FFALSE, add = TRUE);
                 axis(1); axis(2) } )

The difference is that I specified the x and y values. Does anybody know how to get both?

Thnaks in advance

You forgot x and y in the contour call:

x<-c(1:10)
y<-c(1:10)
z<-matrix(x,nrow=length(x),ncol=length(y))
filled.contour(x,y,z,plot.axes = { contour(x,y,z, nlevels = 20, 
                                 drawlabels = TRUE, axes = FALSE, 
                                 frame.plot = FALSE, add = TRUE);
             axis(1); axis(2) } )
