  • 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
  • Numbers at the corners of concentric squares Antsy permutations Can I use my client's GPL software?
  • The error bars are added in at the end using the segments() and arrows() functions.
  • The method below is from Morey (2008), which is a correction to Cousineau (2005), which in turn is meant to be a simpler method of that in Loftus and Masson (1994).

  • This data set is taken from Hays (1994), and used for making this type of within-subject error bar in Rouder and Morey (2005). data <- read.table
  • Our tutorials cover different topics including statistics, data manipulation and visualization!
  • If you want y to represent counts of cases, use stat="bin" and don't map a variable to y.

See ?geom_bar for examples. (Deprecated; last used in version 0.9.2) So anyone knows how to resolve that ?
