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 For each study I have the mean and 95% confidence intervals for both males and females. Are there packages available for this? The steps here are for explanation purposes only; they are not necessary for making the error bars. http://codentropy.com/error-bars/error-bars-below-zero.html
This data set is taken from Hays (1994), and used for making this type of within-subject error bar in Rouder and Morey (2005). data <- read.tableaes or aes_string. http://stackoverflow.com/questions/20197118/dotplot-with-error-bars-two-series-light-jitter
So I needed to layer in the confidence intervals. library(ggplot2) # grab data for males df_m <- data[ , c(1, 2, 4, 5)] df_m$sex <- "m" names(df_m) <- c("ID", "avg", "lower", "upper", "sex") df_m # grab data for females df_f My audience was a general audience so I didn't want to use boxplots or other density types of visualization methods.

Summaryse R I have two questions. > > First, how do I rotate the plot 90 degrees so the group labels are on > the x axis and the response value on the You should, though, also be able to construct a small example dataset that does work without giving away any confidential info. https://www.r-bloggers.com/r-tutorial-add-confidence-intervals-to-dotchart/ Note that tgc$size must be a factor.
We display all the intermediate graphs below together with R code. #creating a ggplot object p <- ggplot(long, aes(y=y, x=female)) p + geom_point() # jittered points and adding a facet p Ggplot2 Dotplot All Rights Reserved. There are many ways to follow us - By e-mail: On Facebook: If you are an R blogger yourself you are invited to add your own R content feed to this I presume this is a technicality due to the a numeric variable being identified as a factor.
Second, I'm having trouble with the group labels. Thanks. –PaoloCrosetto Nov 25 '13 at 19:46 I ended up using yur code (and learning a lot about ggplot2).

If I am fat and unattractive, is it better to opt for a phone interview over a Skype interview? http://codentropy.com/error-bars/how-to-add-error-bars-in-logger-pro.html Understanding within-subjects error bars This section explains how the within-subjects error bar values are calculated. I did find a function "dotplots.errors" available here: http://agrobiol.sggw.waw.pl/~cbcs/articles/CBCS_5_2_2.pdf. I knew that I could use the lines function to add lines to an existing plot.

What I would like to do is something similar to this: I have used several flavours of dotplots (dotplot, dotplot2, Dotplot) but did not quite get there. http://codentropy.com/error-bars/how-to-interpret-error-bars.html 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
However, when there are within-subjects variables (repeated measures), plotting the standard error or regular confidence intervals may be misleading for making inferences about differences between conditions. Geom_errorbar Linetype This can result in unexpected behavior and will not be allowed in a future version of ggplot2. For example: dat <- read.table(header=TRUE, text=' id trial gender dv A 0 male 2 A 1 male
