Re: [R] Mean and individual growth curve trajectories

Hi: Here's another version of the plot using ggplot2: g <- ggplot(sleepstudy, aes(x = Days, y = Reaction, group = Subject, colour = Subject)) g + geom_line(size = 1) + geom_smooth(aes(group = 1), size = 2) + theme_bw() To get rid of the legend, if you so desire, use g + geom_line(size = 1) +

[R] Mean and individual growth curve trajectories

I'm trying to understand how to plot individual growth curve trajectories, with the overall mean trajectory superimposed (preferably in a slightly thicker line, maybe in black) over the individual trajectories. Using the sleepstudy data in lme4, here is the code I have so far: library(lme4) libr
