R plot implicit function outer command
I would like to plot an implicit function of x and y:  1-0.125*y^2-x^2=0.005
I know it can be plotted as a contour plot but have trouble with the "outer" command 
in the following:
  
   `x<-seq(0.4,1.01,length=1000)  
    y<-seq(0,3,length=1000)  
    z<-outer(x,y,FUN="1-0.125*y^2-x^2=0.005")  
    contour(x,y,z,levels=0,drawpoints=FALSE)`

I read the FAQ (7.17) regarding the "outer" command and the need to vectorize the function but am still in a quandry.  

Any help would be greatly appreciated.
Thanks,
Carey
