[R] fill prob. in legend

[Jerome Asselin]

Ok... All we need is an "blank" symbol (such as pch=30(?)).

Now try again...

Jerome

plot(0,0)
legend(0,0,c("blah","blahblah","blahblahblah","blah..."),
pch=c(30,30,22,22),
col=c("green","red","blue","blue"),
lty=c(1,1,2,2),
pt.bg=c("white","white","yellow","orange"),cex=2)
