[R] OT: compare several graphs

[Sven Garbade]

Hi all,

this is OT, but maybe someone can give me a clue. I've got data from eye
tracker experiments (750 data points). These figures show how the data
lock like


|**  *    *****     |***     ******
|  ** ****          |   *   *
|                   |    * *
|                   |     *
|--------------     |---------------

Y axes display velocity, x axes display time, * are the data points. My
question is if there is a method to compare these graphs statistical and
decide if they are different from each other or not. Maybe I can divide
the x axes into several intervals and compare the means?

Thanks for any suggestions,
Sven
