[pstricks] filecontents

[Poul Riis]

When I run the file below several times, each time changing some of the
data points, I get error messages because the data files already exist,
and the old versions are used. I can manually delete the files but isn't
there a way to do it automatically from the latex file?
Furthermore, I would prefer the regression line to be extended to the full
x-interval of the graph window and not only going from the data point with
the minimum x to the data point with the maximum x. Is that possible?
