xyplot: tick marks inside panel
...yplot figure (for example the first from example(lattice) ) I would like to place the tick marks inside the panels instead of outside.

adding multiple fitted curves to xyplot graph
...t(df$factor1),fit.curve) I would like to add the 4 curves corresponding to these 4 fits to my graphic. The elegant way would be a custom panel function I suppose, but I haven't been able to write one up... Could someone help me out on this please? In advance thanks very much!!!
