[R] problems with rexp ?

[Ole Christensen]

Hi Juan

It looks constant to me. Note the range of the values on the second axis
!!!
Sometimes you even get a warning about this

Warning message: 
relative range of values =  22.5 * EPS, is small (axis 2).


Note also: By calling your variable ``data'' you are over-writting a
function of the same name
(I do not think it did any harm in your example).

Cheers Ole
