Hello r-group
I have a question to the ks.test.
I would expect different values for less and greater between data1 and
data2.
Does anybody could explain  my point of misunderstanding the function?

The help page says:

     This is a comparison of cumulative distribution
     functions, and the test statistic is the maximum difference in
     value, with the statistic in the '"greater"' alternative being D^+
     = max_u [ F_x(u) - F_y(u) ].

data1 and data2 have the same empirical CDF, so should and do give the 
same value of the test statistic.

We cannot know what you misunderstanding is, since you have not 
explained your expectations.
