I do not understand what you want? What is 10.2

maybe names.arg is what you want.

barplot (chromosome, col="purple", xlab="Oryza sativa Chromosomes", border
= NA, space = 5, ylim = c(0,45), names.arg=chromosome, axes=F)

> I also want to set the scale of y axis from 0,5,10,15,20,25,30,35,40,45 
i.e

use axes=F and

axis(2, at=seq(0,45,5))
