Dear all, parallel(~iris[1:4], groups = Species, iris, par.settings = simpleTheme(lwd = c(1,3,1), lty = c(1,1,2), col.line = 1), auto.key = T) Despite the use of par.settings and simpleTheme, the lines in the key and graph are not the same. Any suggestions why? Regards, Marcin [[alternative HTML version deleted]]
