Geom_errorbar Linetype 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).

Note that we have to provide (or compute) the ymin and ymax values for the error bars ourselves (the errorbar geom does not automatically compute a confidence interval).

If you want y to represent counts of cases, use stat="bin" and don't map a variable to y. par(mar = c(5, 6, 4, 5) + 0.1) plotTop <- max(myData$mean) + myData[myData$mean == max(myData$mean), 6] * 3 barCenters <- barplot(height = myData$mean, names.arg = myData$names, beside = true, las =
