    library(grid)

plot(0:10, 0:10, type="n", xlab="X", ylab="Y")
grid.roundrect(gp=gpar(fill="#00000000", col="grey"))

    enter image description here

    If you find the borders are being cut off, you can always reduce the size of the rounded rectangle:

    plot(0:10, 0:10, xlab="X", ylab="Y")
grid.roundrect(height=0.99, width=0.99, gp=gpar(fill="#00000000", col="grey"))

    enter image description here
