X axis does not match barplot

Question

I used barplot() function to create a stacked chart from matrix.

Matrix looks like this:

1 0.989013 0.010987
2 0.999990 0.000010
3 0.999990 0.000010         


        

Answer 1

Look at the updateusr function in the TeachingDemos package. This function will change or "update" the user coordinates of a plot. The example shows changing the coordinates of the x axis of a barplot to match the intuitive values for additional plotting.
