Have you tried downloading the latest version of errorbar_groups (updated on Apr 8, 2015)? The method in Morey (2008) and Cousineau (2005) essentially normalizes the data to remove the between-subject variability and calculates the variance from this normalized data. # Use a consistent y Our tutorials cover different topics including statistics, data manipulation and visualization!

The normed means are calculated so that means of each between-subject group are the same. This can be done in a number of ways, as described on this page.

Thanks for keeping me posted. Adding Standard Error Bars In R Added option to skip plotting the error bars altogether. 22 Jan 2015 1.5 Corrected an issue where no error bar was plotted in the case that one side (upper or lower) The natural way for statisticians is to use a boxplot, and ggplot2 makes that easy: qplot(class, hwy, fill=factor(year), data=mpg, geom="boxplot", position="dodge")+theme_bw() But Jarrett Byrnes, a marine community biologist, wanted to use Thanks for sharing some alternatives that preserve more information about the data's distribution.

The points are drawn last so that the white fill goes on top of the lines and error bars. ggplot(tgc, aes(x=dose

• Wouldn't it be nicer if we could group the bars by number of cylinders or number of gears?
• In this case, the column names indicate two variables, shape (round/square) and color scheme (monochromatic/colored). # Convert it to long format library(reshape2) data_long
• Turns out, R makes this pretty easy with just a couple of tweaks to our code!
• We use srt = 45 for a # 45 degree string rotation text(x = barCenters, y = par("usr")[3] - 1, srt = 45, adj = 1, labels = myData\$names, xpd =
• I've corrected the problem and re-uploaded the function.
• The standard deviation is used to draw the error bars on the graph.

However, it will be fantastic to understand how or why the following lines of code work:groupwidth = min(0.8, numbars/(numbars+1.5)); andx = (1:numgroups) - groupwidth/2 + (2*i-1) * groupwidth / (2*numbars); Thank Can I use this Grouped bar function without having Image processing toolbox? I.e., instead of this: head(myData) cyl gears mean sd n se names 4 3 21.500 NA 1 NA 4 cyl / 3 gear 4 4 26.925 4.807360 8 1.6996586 4 cyl get redirected here Here, we'll start by widening the plot margins just a tad so that nothing runs off the edge of the figure (using the par() function).
