[R] legend with density and fill

[Simon Pickett]

Hi,

I am trying to make a legend with four symbols as follows

1.white box
2.black box
3.clear box (same as background)
4.clear box with shading lines

but the shading lines arent showing...

here is my code.

par(bg="lightyellow")
barplot(c(seq(1,6,1)))
legend(8.5,0.3, bty="o", legend=c("young","old","male","female"),
col="black",cex=1.5,
fill=c("white","dark grey",0,0),density=c(NA,NA,0,100),angle=45)

any suggestions much appreciated,
Thanks, Simon.
