Hi R-Users,

I am working with sm.ancova (in the package sm) and I have two problems with the graph, which is automatically generated when sm.ancova() is run.

1-Besides of the fitted lines, the observed data appeared automatically in the graph. I prefer that only fitted lines appear. I check the sm.options, but I could not find the way that  the observed data do not appear in the graph.

2-I would like to change the size of the numbers in the axis. Again,  I check the sm.options, but I could not find the correct way.



Thank you in advance,

Lucía
