It describes the effect of Vitamin C on tooth growth in Guinea pigs. It was working for me until I updated to the latest version of ggplot2 (2.2.0). first order condtion of Lagrangian What is a tire speed rating and is it important that the speed rating matches on both axles? Error Bars In R My code is as follows: mydata<-as.data.frame(mydata) mydata$groupvar<-cut(mydata$group,c(0,0.2,1)) mydata<-mydata[,-4] library("reshape") changedata <- melt(mydata,id=c("groupvar"),variable_name="Ray") library("plyr") arrangedata <- ddply(changedata, c("groupvar","Ray"), summarise, N = length(value), mean = mean(value), sd = sd(value), se = sd /
The points are drawn last so that the white fill goes on top of # the lines and error bars. Ggplot Confidence Interval Understanding within-subjects error bars This section explains how the within-subjects error bar values are calculated. These values can diverge when there are between-subject variables. From there it's a simple matter of plotting our data as a barplot (geom_bar()) with error bars (geom_errorbar())!

This can result in unexpected behavior and will not be allowed in a future version of ggplot2. Browse other questions tagged r ggplot2 plyr or ask your own question. With stat="bin", it will attempt to set the y value to the count of cases in each group. I have a new guy joining the group.
If you want y to represent counts of cases, use stat="bin" and don't map a variable to y. In the geom_errorbar code, ymin and ymax are the top and bottom of the error bars (defined here as mean +/- sd), and width defines how wide the error bars are. ggplot offers geom_errorbar() but I would be glad to know different ways for deriving the standard errors(deviation) so as to calculate the errorbar limits(CI). One way that we can construct these graphs is using R's default packages.
