Any thoughts? Do these physical parameters seem plausible? with mean 1.1 and unit variance. It can also make a horizontal error bar plot that shows error bars for group differences as well as bars for groups. http://stackoverflow.com/questions/13032777/scatter-plot-with-error-bars

Choose your flavor: e-mail, twitter, RSS, or facebook... rather than a function of the alpha level. The graph of individual data shows that there is a consistent trend for the within-subjects variable condition, but this would not necessarily be revealed by taking the regular standard errors (or R Summaryse Beyond this, it's just any additional aesthetic styling that you want to tweak and you're good to go!

Words that are both anagrams and synonyms of each other How to Usage geom_errorbar(mapping = NULL, data = NULL, stat = "identity", position = "identity", ...) Arguments mapping The aesthetic mapping, usually constructed with aes or aes_string.

Can also be combined with such functions as boxplot to summarize distributions. Understanding within-subjects error bars This section explains how the within-subjects error bar values are calculated. The key step is to precalculate the statistics for ggplot2. Plot Mean And Standard Deviation In R From there it's a simple matter of plotting our data as a barplot (geom_bar()) with error bars (geom_errorbar())!

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). Let's look at our same Gaussian means but now compare them to a Gaussian r.v. To modify that, change the s.e. #Consider the case where we get stats from describe temp <- describe(attitude) error.bars(stats=temp) #these error bars will be just one s.e. #adjust the s.e. http://setiweb.org/error-bars/plot-with-error-bars-idl.php See ?geom_bar for examples.
