Here are the actual functions (from **package ChemoSpec). >** seX <- function (x) sd(x, na.rm = TRUE)/sqrt(length(na.omit(x))) >

See these papers for a more detailed treatment of the issues involved in error bars with within-subjects variables. Note that dose is a numeric column here; in some situations it may be useful to convert it to a factor. tg <- ToothGrowth data <- read.table

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 ggplot

Understanding within-subjects error bars This section explains how the within-subjects error bar values are calculated. This can be done in a number of ways, as described on this page. In particular, rxnNorm looks like the plot you are trying to produce, plus it gives you a variety of options in terms of the summarizing stats and decorations to the plot. Error Bar In R For horizonal charts, ylim is really the x-axis range, excluding differences.

It's not quite as pretty as a ggplot solution, but quite a bit more general, and a lifesaver for moderately complex GLMs. Barplot With Error Bars R If it is a numeric vector, then it will not work. # Use dose as a factor rather than numeric tgc2 <- tgc

- That is more clear than the clutter of code in your example.
- Below, I go through the code for the ANOVA by hand and calculate the 95% CIs by hand also (with standard error estimated from the total residual variance, not just the
- Defaults to blank for horizontal charts.
- The normed means are calculated so that means of each between-subject group are the same.
- Not with interaction.plot(), as far as I know.

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. http://caribtechsxm.com/error-bar/r-plot-error-bar.php For example: Another possibility is the function lineplot.CI from the package sciplot (a wrapper that adds SE bars to the output from interaction plots).
