Hello list, I'm trying to plot nls profiles, but the plot.profile.nls function in R doesn't seem to accept any plot.default variables. Specifically, I'd like to be able to change the x-axis title and the colors to black and white. Has anyone had any luck with this? If not, is there a way to override to plotting colors, perhaps in par()?
No. The authors hardcoded all these. Take a copy of the function and modify it to suit your purposes.
But as they hardcoded the colours to numbers, see ?palette .
Thanks, Sam fm1 <- nls(demand ~ SSasympOrig(Time, A, lrc), data = BOD) pr1 <- profile(fm1, alpha = 0.05) opar <- par(mfrow = c(2,2), oma = c(1.1, 0, 1.1, 0), las = 1) plot(pr1, conf = c(95, 90, 80, 50)/100) # works fine plot(pr1, conf = c(95, 90, 80, 50)/100,xlab=expression(theta),col=1) # doesn't change
