I don't think that makes sense. Star graphs are only defined for an ensemble of rowss, at least with the default setting of 'scale=TRUE'. > The following give an incorrect graph for the first two cars : > stars(mtcars[1:2, 1:7]) Looks correct to me. 1st two models are identical on five variables, and the remaining two are scaled to [0,1], which in this case means that you get two zeros for the first car and two ones for the other. > The following gives the correct graphs for all cars: > stars(mtcars[1:32, 1:7]) > > How can I have correct graphs for a selection of lines ? First define "correct". You can use scale=FALSE and do the scaling yourself in some way that is independent of the subset chosen. -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
