Value Graphic output showing the means + x These confidence regions are based upon normal theory and do not take into account any skew in the variables. Defaults to blue. ... One way that we can construct these graphs is using R's default packages. These values can diverge when there are between-subject variables.

Alternatively, plots of means +/- one standard deviation may be drawn.

with mean 1.1 and unit variance. If, alternatively, a matrix of statistics is provided with column headings of values, means, and se, then those values will be used for the plot (using the stats option). Built by staticdocs.
