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. Here is a data set (from Morey 2008) with one within-subjects variable: pre/post-test. ## conf.interval: the percent range of the confidence interval (default is 95%), # Ensure that the betweenvars and withinvars are factors, "Automatically converting the following non-factors to factors: ", # Drop all the unused columns (these will be calculated with normed data), # Collapse the normed data - now we can treat between and within vars the same, # Apply correction from Morey (2008) to the standard error and confidence interval, # Get the product of the number of conditions of within-S variables, # Combine the un-normed means with the normed results. 3 46.0 49.7 ggplot(dat_long, aes(x = Batter, y = Value, fill = Stat)) + geom_col(position = "dodge") Created on 2019-06-20 by the reprex package (v0.3.0) B 1 male 8 ## withinvars: a vector containing names of columns that are within-subjects variables #> 8 8 pretest 54.3 Ah, the barplot. #> 4 4 49 Round Monochromatic Highlight a Bar in Barplot with ggplot2 in R: First Try A simple way to highlight a bar in barplot is to simply use the new variable that we created with the fill argument in ggplot.
