Hi Gundala,
If you want your plotting axes to appear in colour,
try
par(fg = "red") # will colour all foreground stuff in red, including the
axes.

This does not help since the new axes are not of the same length as the
default 'box' that you get around a plot.

The matrix will give you user id and number of sites visited, provided user
id ranges from 1 to the number of users. There must be a way to do this
using table, but I cant figure it out.
