Re: [R] Overlay boxplot and scatter.smooth line
Same thing using ggplot... # your data x <- c(rep(1,100),rep(2,100),rep(3,100)) y <- c(rnorm(100,1),rnorm(100,2),rnorm(100,3)) df <- data.frame(x=x, y=y) library(ggplot2) ggp <- ggplot(df) + labs(x="X", y="Y") ggp <- ggp + geom_boxplot(aes(x=factor(x), y=y)) ggp <- ggp + geom_smooth(formula=y~x, aes(x=x, y=y), method="loess", se=F) ggp Setting method="lm" above would plot linear model instead of loess, setting se=T (the default) would plot 95% CL for the model. Adding the line: ggp <- ggp + stat_summary(fun.data="mean_cl_normal", aes(x=factor(x),y=y), size=1.2, color="red") ggp will overlay mean and 95% CL (assuming normal distribution of error) at each level of x. -Original Message- From: Johannes Radinger [mailto:johannesradin...@gmail.com] Sent: Tuesday, November 19, 2013 10:01 AM To: Adams, Jean Cc: R help Subject: Re: [R] Overlay boxplot and scatter.smooth line Thanks...that works great! /J On Tue, Nov 19, 2013 at 2:39 PM, Adams, Jean wrote: > Use lines() with loess.smooth() instead of scatter.smooth() to add to > the already existing boxplot.

Re: [R] Overlay boxplot and scatter.smooth line
Use lines() with loess.smooth() instead of scatter.smooth() to add to the already existing boxplot. For example, boxplot(y~x) lines(loess.smooth(x, y)) Jean On Tue, Nov 19, 2013 at 4:43 AM, Johannes Radinger < johannesradin...@gmail.com> wrote: > Hi, > > I'd like to plot a boxplot and use a scatter.smooth line plot as an overlay > for this plot. > This works except for the problem that the x-axis ticks for both plots are > differently spaced: > The boxplot ticks are closer and the space between the outer most boxplots > and the plot region (box) is larger for boxplots than for the > scatter.smooth plot.
