Is it a fallacy, and if so which, to believe we are special because our existence on Earth seems improbable? Means and standard errors are calculated from the raw data using describe.

Thankfully, there is!

The graph of individual data shows that there is a consistent trend for the within-subjects variable condition, but this would not necessarily be revealed by taking the regular standard errors (or If you have within-subjects variables and want to adjust the error bars so that inter-subject variability is removed as in Loftus and Masson (1994), then the other two functions, normDataWithin and Comments are closed.

However, when there are within-subjects variables (repeated measures), plotting the standard error or regular confidence intervals may be misleading for making inferences about differences between conditions. http://monkeysuncle.stanford.edu/?p=485 All Rights Reserved.

You should better use the errbar function from the Hmisc package: d = data.frame( x = c(1:5) , y = c(1.1, 1.5, 2.9, 3.8, 5.2) , sd = c(0.2, 0.3, 0.2, It's also a good habit to specify the upper bounds of your plot since the error bars are going to extend past the height of your bars. ggplot2 0.9.3.1 Index Error bars. Source Gears", border = "black", axes = TRUE, legend.text = TRUE, args.legend = list(title = "No.

The regular error bars are in red, and the within-subject error bars are in black. # Instead of summarySEwithin, use summarySE, which treats condition as though it were a between-subjects If at least one of the confidence intervals includes zero, a vertical dotted reference line at zero is drawn. Value Graphic output showing the means + x These confidence regions are based upon normal theory and do not take into account any skew in the variables. If, alternatively, a matrix of statistics is provided with column headings of values, means, and se, then those values will be used for the plot (using the stats option).
