I found two nice resources that demonstrate the plotting of error bars with R and in this post I illustrate them with simple examples. One within-subjects variable Here is a data set (from Morey 2008) with one within-subjects variable: pre/post-test. dfw <- read.table(header=TRUE,

Error.bar Function R

Type used for horizontal bars only. If you have within-subjects variables and want to adjust the error bars so that inter-subject variability is removed as in Loftus and Masson (1994), then the other two functions, normDataWithin and lwd line width for line segments (not main line) pch character to use as the point.

  1. In this case, we’ll use the summarySE() function defined on that page, and also at the bottom of this page. (The code for the summarySE function must be entered before it
  2. If you want y to represent counts of cases, use stat="bin" and don't map a variable to y.
  3. This can result in unexpected behavior and will not be allowed in a future version of ggplot2.
  4. Defaults to 0.015.
  5. Gears") In all cases, you can fine-tune the aesthetics (colors, spacing, etc.) to your liking.

  8. Each feature conveys a different message and this paper on error bars in experimental biology explains it very nicely.

See ?geom_bar for examples. (Deprecated; last used in version 0.9.2) p p + geom_pointrange(limits) p + geom_crossbar(limits, width=0.2) # If we want to draw lines, we need to manually set the stat The statistical transformation to use on the data for this layer. Let's make the abscissa just the number of these "measurements", so x <- 1:n. Errbar R Share Online.

The error bars are added in at the end using the segments() and arrows() functions. Ggplot2 Error Bars myData$se <- myData$x.sd / sqrt(myData$x.n) colnames(myData) <- c("cyl", "gears", "mean", "sd", "n", "se") myData$names <- c(paste(myData$cyl, "cyl /", myData$gears, " gear")) Now we're in good shape to start constructing our plot!

For the latter type of plot, the lower x-axis scale corresponds to group estimates and the upper scale corresponds to differences. In this case, the column names indicate two variables, shape (round/square) and color scheme (monochromatic/colored). # Convert it to long format library(reshape2) data_long If your data needs to be restructured, see this page for more information.
