I know this is an old thread but set the fill and the color of the element_rect layer equal to the background color
I don't know whether this will work with ggplot2 but in a visual I made based on the fmsb package I was able to work around this issue by using the par() function before the plotting was called:
# generic par function for graphical elements, call before the plotting
# this is wear the plotting of the visual actually happens radarchart(data)
