I want to plot bars on the Y-axis extending on both the sides.
Suppose I have a vector v which I want to plot.
v<-c(20, 40, 60, 120, 140, 180)
and I want my y-axis to be at x=100, instead of x=0 and then the values less than 100 to be marked to the left of the y-axis using bars and those greater than 100 to the right. How can I get such a barplot?
