I'm sorry I didn't give the correct code, or explaination; the
shape=pch doesn't work anymore. For example this used to work, but no
longer can accept continuous values:
#example code
a <- 1:10
b <- 1:10
pch <- 1:10
q <- data.frame(a,b,pch)
qplot(a,b, shape=pch)
many thanks,

Is there a way to use a continuous variable to pch in qplot? I
believe this worked in previous version. I need to specify certain
values of a shape for particular points so that multiple graphs all
show the same shapes for the same streams. I have gone to the
original data and added a pch column that I would like to use to
specify the shapes to pch in qplot. Any help would be greatly
appreciated.
#example code
a <- 1:10
b <- 1:10
pch <- 1:10
q <- data.frame(a,b,pch)
qplot(a,b, pch=pch)
Many thanks,
