Hello, hopefully simple question, but I cannot find the answer. I need to change the color from the standard default. Still want the scaled colors, but need different colors for different graphs. Code is: wireframe(z ~ y*x, mat.df, drape = TRUE, zlab = list("Water mass error (%)",rot=92), zlim=c(-50,180), xlab = list("Resistance error (%)",rot=16), ylab = list("Length error (%)",rot=118), scales = list(arrows = FALSE), screen = list(z = 20, x = -57, y = 5)) Thanks ahead of time. -- M.
