[R] outlining symbol in legend with blackline

[Yasir Kaheil]

yes use plotting chars 22, 21
replace your legend statement with:

legend(x="topright", legend=c("2006 mean", "2007 mean", "2008 mean", 
"1964-2005 mean \n max and min flows "), pch=c(22, 22, 22, 21), 
col=c(1,1,1,1), pt.bg=c(grey.colors(3, gamma=4),"black"), cex=1.5) 
box(which="plot", lty="solid")
