Yes indeed. Here we are:

# example without asp

x<-seq(1,10,l=20)
y<-seq(1,5,l=20)
z<-rnorm(400)
zmat<-matrix(z,ncol=20)
filled.contour(x,y,zmat,frame.plot = FALSE)

# example with asp (eg: a geographic map projected where x and y display 
ratio must be 1

x<-seq(1,10,l=20)
y<-seq(1,5,l=20)
z<-rnorm(400)
zmat<-matrix(z,ncol=20)
filled.contour(x,y,zmat,frame.plot = FALSE,asp=1)

I wonder if there is a way to resize the legend in such a way it as the 
same height as the image displayed...

Best,
