This can be done in a number of ways, as described on this page. female, etc.). View(mtcars) We begin by aggregating our data by cylinders and gears and specify that we want to return the mean, standard deviation, and number of observations for each group: myData <- PLAIN TEXT R: y1 <- rnorm(500, mean=1.1) y1 <- matrix(y1,100,5) y1.means <- apply(y1,2,mean) y1.sd <- apply(y1,2,sd) yy <- matrix(c(y.means,y1.means),2,5,byrow=TRUE) ee <- matrix(c(y.sd,y1.sd),2,5,byrow=TRUE)*1.96/10 barx <- barplot(yy, beside=TRUE,col=c("blue","magenta"), ylim=c(0,1.5), names.arg=1:5, axis.lty=1, xlab="Replicates",

Built by staticdocs. 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. This can result in unexpected behavior and will not be allowed in a future version of ggplot2.

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).

The regular error bars are in red, and the within-subject error bars are in black. # Instead of summarySEwithin, use summarySE, which treats condition as though it were a between-subjects http://www.sthda.com/english/wiki/ggplot2-error-bars-quick-start-guide-r-software-and-data-visualization If you want y to represent counts of cases, use stat="bin" and don't map a variable to y. Error Bars On Line Graph Excel PLAIN TEXT R: error.bar <- function(x, y, upper, lower=upper, length=0.1,...){ if(length(x) != length(y) | length(y) !=length(lower) | length(lower) != length(upper)) stop("vectors must be same length") arrows(x,y+upper, x, y-lower, angle=90, code=3, length=length, Line Graph With Error Bars Stata Three dose levels of Vitamin C (0.5, 1, and 2 mg) with each of two delivery methods [orange juice (OJ) or ascorbic acid (VC)] are used : library(ggplot2) df <- ToothGrowth

main a main title for the plot, see also title. Check This Out It can also make a horizontal error bar plot that shows error bars for group differences as well as bars for groups. You will be notified about this book. Let's try grouping by number of cylinders this time: limits <- aes(ymax = myData$mean + myData$se, ymin = myData$mean - myData$se) p <- ggplot(data = myData, aes(x = factor(cyl), y = R Plot Error Bars

Here is my favourite workaround, the advantage is that you do not need any extra packages.

Gears", ylab = "Miles per Gallon", border = "black", axes = TRUE) # Specify the groupings. Understanding within-subjects error bars This section explains how the within-subjects error bar values are calculated.
