[R] drawing an axis using axis command

[Greg Snow]

If the structure is your xx variable, then you are creating a plot that goes from 1911 to 2006 (plus a little to either side), then asking the axis function to draw and label an axis from 1 to 11, which is very far off the plotting device to the left.  Try giving the axis function a list of values actually within the range of the data that you plot.
