Hello!

I am using ggplot2:

ggplot(myplotdata, aes(x=att_levels, y=WTP)) +
                geom_bar(stat="identity",fill="dark orange",colour="black",
alpha = 1,position = "identity") +

geom_text(aes(label=WTP),colour="black",size=4,hjust=1.1,position='dodge') +
                coord_flip() +
                xlab("") +
                ylab("")

How could I get rid of the border lines on the bars (just leave the fill,
but no border)?
Thank you!
