## Contents |

Excluding **N (count).** For example, how can I create a bar graph and add confidence interval? 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). The you will have a different length of the small bars on the right an the left side (the epsilon follows the x-values). news

You should better use the errbar function from the Hmisc package: d = data.frame( x = c(1:5) , y = c(1.1, 1.5, 2.9, 3.8, 5.2) , sd = c(0.2, 0.3, 0.2, Cylinders", x = "topright", cex = .7)) segments(barCenters, tabbedMeans - tabbedSE * 2, barCenters, tabbedMeans + tabbedSE * 2, lwd = 1.5) arrows(barCenters, tabbedMeans - tabbedSE * 2, barCenters, tabbedMeans + See ?geom_bar for examples. (Deprecated; last used in version 0.9.2) p Mapping a variable to y and also using stat="bin".

Plot Error Bars In R This can be done in a number of ways, as described on this page. Summaryse R Aesthetics geom_errorbar understands the following aesthetics (required aesthetics are in bold): **x** **ymax** **ymin** alpha colour linetype size width Examples # Create a simple example dataset df # Because the bars
