Hello,
I guess a have a very simple problem though up to now couldn't solve it:
I want to plot two datasets wihtin one plot like plot(x) provides it for 
one dataset(type="b" that is: points connected by lines).
Example data 'x':
Befragung1   Befragung2   Befragung3   Geschlecht
2.25   2.34   1.78   weiblich
1.34   3.45   2.23   maennlich
The two rows of the example above form two datasets. Now I'm looking for 
something like plot(~x |Geschlecht, ... ): X-axis containing 
Befragung1...3, y-axis containing the values given by the matrix 'x', 
points within one dataset (row of 'x') connected by lines.
I already tried various possibilities provided by 'lattice' or 'grid'  - 
but there seems to be a basic misunderstanding on my side so that I 
could not produce any good result.
Would by very happy to get some hints!
Greetings
Karsten Rincke
