Ggplot2 Error Bars Position


The "identity" argument tells ggplot to plot y at x. Note that tgc$size must be a factor. How can I separate the errorbars for different indices? How do I get geom_bar to agree with the other two? Source

data A layer specific dataset - only needed if you want to override the plot defaults. This is useful e.g., to draw confidence intervals. I think I have misunderstood the meaning of 'group'. But in this line of code, you unset the linetype=group mapping, so group is not a grouping variable for the error bars: limits <- aes(ymax=mean + std.error, ymin=mean - std.error, linetype=NULL)

R Calculate Standard Error

With stat="bin", it will attempt to set the y value to the count of cases in each group. Downgrading to 0.8.9 fixed this problem. On 0.9.0, the code below does not dodge the error bars. This encourages us to continue....

But here is a dput of the actual data (which is pretty simple), along with a pared down version of the ggplot call that creates the failure to dodge error bars. See these papers for a more detailed treatment of the issues involved in error bars with within-subjects variables. My sense is that it has to do with faceting and the order of the data.

This can result in unexpected behavior and will not be allowed in a future version of ggplot2. Geom_errorbar Horizontal How did Smith get to see Cypher alone? An error bar is similar to a pointrange (minus the point, plus the whisker).

You signed in with another tab or window. For easily getting the statistics by group, we have used a package called "doBy", library(ggplot2) library(doBy) hsb2 <- read.table('http://www.ats.ucla.edu/stat/data/hsb2.csv', header=TRUE, sep=",") hsb2$female <- factor(hsb2$female, labels = c("male", "female")) Step 1.

I see what you mean that unsetting linetype for the error bars should turn off the dodge positioning, so the undodged plot is quite sensible. asked 3 years ago viewed 4680 times active 1 year ago Linked 2 Force error bars to be in the middle of bar 1 Plotting error bars Related 1bar width in
