qplot(..., size=0.5): get rid of the 0.5 in the legend

[Agustin Lobo]

In
qplot(runif(100),runif(100),colour=c(rep(1,50),rep(2,50)),size=0.5)

I get a "0.5 " field in the legend, which makes sense if size is a
variable, but does not if size is fixed.
How can I manage to do not get that size in the legend?

Thanks

Agus

Maybe this

qplot(runif(100),runif(100),colour=c(rep(1,50),rep(2,50)),size=0.5) + scale_size("size")

Hi:

An alternative to Scott's solution is

qplot(runif(100),runif(100),colour=c(rep(1,50),rep(2,50)),size=I(0.5))

HTH,
Dennis

Hi 

try this 

qplot(runif(100),runif(100),colour=c(rep(1,50),rep(2,50))) +geom_xx(size=0.5)

qplot(runif(100),runif(100),colour=c(rep(1,50),rep(2,50)))+geom_point(size=5)
