Strange, indeed. The problem arises also with other examples : > line(1:8,1:8) Call: line(1:8, 1:8) Coefficients: [1] -1.125 1.250 > line(1:9,1:9) Call: line(1:9, 1:9) Coefficients: [1] -1.0 1.2 _________________________________ St�phane Adamowicz Inra, centre de recherche Paca, unit� PSH 228, route de l'a�rodrome CS 40509 domaine St Paul, site Agroparc 84914 Avignon, cedex 9 France stephane.adamow...@avignon.inra.fr tel. +33 (0)4 32 72 24 35 fax. +33 (0)4 32 72 24 32 do not dial 0 when out of France web PSH : https://www6.paca.inra.fr/psh web Inra : http://www.inra.fr/ _________________________________ [[alternative HTML version deleted]]
