[R] filled contour plot with contour lines

[Steve_Friedman at nps.gov]

I'm stumped,  can anyone find my error in this sequence.

 for(j in 1:(varsize[4]-1))
      temp <- get.var.ncdf(nc=input,
varid="p_foraging",c(1,1,j),c(varsize[1],varsize[2],1))
         filled.contour(x, y, temp, color = terrain.colors,
             plot.title = title(main = paste("Everglades Wood Stork
Foraging Potential \nYear", (2000+j)),
             xlab = "UTM East", ylab = "UTM North") ,
             plot.axes = { contour(temp, add=T)
                axis(1, seq(450000 , 580000, by = 10000))
                axis(2, seq(2800000,4000000, by = 10000)) },
             key.title = title(main="Probability") ,
             key.axes = axis(4, seq(0 , 1 , by = 0.1))


The routine will work in a modified form without adding the coordinates
(the axis lines) but when I include these the routine produces various
errors, such as "dimension mismatch", or "unexpected end encountered."

I tried to follow the example on filled.contour help page.

Thanks in advance
