Dear all,

I have some data.frame and I would like (1) change the format of y=axis to
escape of scientific format (like 1e+05...) and (2) label the value or other
variable on the top of the bar.

df<-data.frame(x=1:6,y=c(100,500,1000,25000,500000,1000000))
barplot(df$y,names.arg=df$x)

Thanks in advance,
