Dear All,

I am newbie to R, and I wanted to plot a barplots with R and in such a way that It will also show me position which I can plot on the bar line.

Here is my code that I am using to plot,

> chromosome <- c(40.2, 35.6, 36.1, 29.6, 31, 29.6, 31, 29.4, 28.2, 23, 23,
>barplot (chromosome, col="purple", xlab="Oryza sativa Chromosomes", border
= NA, space = 5, ylim = c(0,45))

I wanted to mark the position say on chromosome 1 (40.2) I need to mark 10.2 and on other also.
I also want to set the scale of y axis from 0,5,10,15,20,25,30,35,40,45 i.e gap of 5 instead of 10.

please help me to solve my query....gurus.

Thank you
