Hi experts,
I was graciously offered a function to enhance abline by restricting the
extent of the line to less than the plotting region. This seems a useful
idea, and it looked like the easiest way to program it was to set up a
clipping region with clip, draw the abline and then restore the

Your point is well taken, but it also raises a number of issues
(post-install testing to name one) for which the R-devel list would be

You may want to consider a dotchart instead of a barplot. Then you can
distinguish between groups by using symbols, grouping, and labels rather than
depending on colors/shades of grey.

Dear Felipe,
You will need to do some reading on factors. Although the labels of a
factor can be 'numeric' try are actually just string representing
numbers. Internally factors are coded as numbers: 1 for the first level,
2 for the second and so on. That's why you run into trouble with

I've started to learn about neural networks and the first examples

AND gate. I've implemented it as a perceptron with no hidden layers,
and I've done it this way because so far is the only way I've learned.

The only comprehensive way to do this would be to change R's internaal
print mechanisms. (Note that changing 0. to . breaks the layout:
changing '0.' to ' .' would be better.)
But you haven't told use why you would want to do this. Leaving off
leading zeroes makes output harder to read for
??'normal distribution' seems to do rather well. If you know that you
want results from 'stats' you can confine the search to that package.
'normal' is such an overloaded word that searching for it is going to
be overwhelming. At least 'Normal' is AFAIR only used in one sense in
statistics.
