For example: dat <- read.table(header=TRUE, text=' id trial gender dv A 0 male 2 A 1 male To get the correct x values we could either find them by trial and error, or get them directly from the barplot. The segments() command lets you draw line segments, provided you specify the coordinates of the beginning and end of the segments.

These are basic line and point graph with error bars representing either the standard error of the mean, or 95% confidence interval. # Standard error of the mean ggplotCousineau (2005) essentially normalizes the data to remove the between-subject variability and calculates the variance from this normalized data. # Use a consistent y How to compute the upper and lower values of the confidence interval for the standard error The first question is easy to answer. http://axishost.net/error-bar/error-bars-on-a-graph.php Welcome to STAT 485 - Intermediate Topics in R Statistical Language!
