The standard deviation is used to draw the error bars on the graph.

Now have a look at the arguments to arrows. Ggplot2 Error Bars First, the function checks that its argument is there, and is an object of class "dstat". By creating an object to hold your bar plot, you capture the midpoints of the bars along the abscissa that can later be used to plot the error bars. Defaults to blank for horizontal charts.

  2. See these papers for a more detailed treatment of the issues involved in error bars with within-subjects variables.
  3. Just for fun with the help of other stackoverflowers.
  4. Here, we'll start by widening the plot margins just a tad so that nothing runs off the edge of the figure (using the par() function).
  5. The un-normed means are simply the mean of each group.
  6. Solution To make graphs with ggplot2, the data must be in a data frame, and in “long” (as opposed to wide) format.

In order to get bars going up and down, there will have to be two sets of starting points. These libraries are free forever.

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.
