R help - Jun 2011 - The simplest bar graph with ggplot is difficult to realize

Dear all,
What is the simplest way of producing a bar graph using ggplot but
avoiding calling qplot?

That is, given:
d <- data.frame(x=seq(1,5), y=seq(1,5))

Why does the following line return an error?
ggplot(d, aes(x=x, y=y)) + stat_identity() + geom_bar(bindwidth=1)

Thanks in advance,
jcb!

Hi Juan,
Each geom can have it's own stat, so stat_identity() doesn't change
the stat used by geom_bar(). You need

ggplot(d, aes(x=x, y=y)) + geom_bar(stat="identity")

Best,
Ista
