John,

That still leaves a string of identical numbers in the vector.

Shane,

perhaps jitter(X,1,0.0001)

Subject: [R] XYZ data

I have x, y, z data. The x, y fields dont change but Z does. How do I add
a
very small number onto the end of each x, y data point.

For example:

Original (X)              Original (Y)                 Original (Z)
15                               20                              30
15                               20                              40




New (X)              New (Y)                 New (Z)
15.00001             20.000001              30
15.00002             20.000002              40


Thanks
