You haven't wrapped p in the print command, which is one of the ways to
make sure the plot gets printed when we need it.
print(p+geom_point(aes(size=3))) does the trick

Dear all
I want to save several ggplots in one pdf document. I tried this
for (i in names(iris)[2:4]) {
p<-ggplot(iris, aes(x=Sepal.Length, y=iris[,i], colour=Species))
p+geom_point(aes(size=3))
}
with different variations of y input but was not successful. In past I
used qplot in similar fashion which worked
for(i in names(mleti)[7:15]) print(qplot(sito, mleti1[,i],
facets=~typ,ylab=i, geom=c("point", "line"), colour=ordered(minuty),
data=mleti1))
So I wonder if anybody used ggplot in cycle and how to solve input of
variables throughout cycle
Thank you
Petr
