[R] graph shading is overlaying axes

[Dean1]

How can I resolve this problem?...

As a general example,
plot (1:4)
polygon(c(0,0,5,5),c(0,5,5,0), border="lavenderblush1", col =
"lavenderblush1")
###see how this overlays the axes lines

#I have tried...
for (k in 1:4)  axis(k, lwd.ticks=0, label=F)
#...but this misses the corners


Any suggestions?
