    <p>I seem to have missed a change within how ggplot2 works. I have an example from a statistics textbook (A. Field (2012), Discovering statistics using R, p. 593) which I'm sure worked but now does not produce connection lines between means of grouped data any more.</p> <p>Here's the sample data:</p> <pre><code>participant&lt;-gl(20, 9, labels = c("P01", "P02", "P03", "P04", "P05", "P06", "P07", "P08", "P09", "P10", "P11", "P12", "P13", "P14", "P15", "P16", "P17", "P18", "P19", "P20" )) drink&lt;-gl(3, 3, 180, labels = c("Beer", "Wine", "Water")) imagery&lt;-gl(3, 1, 180, labels = c("Positive", "Negative", "Neutral")) groups&lt;-gl(9, 1, 180, labels = c("beerpos", "beerneg", "beerneut", "winepos", "wineneg", "wineneut", "waterpos", "waterneg", "waterneut")) attitude&lt;-c(1, 6, 5, 38, -5, 4, 10, -14, -2, 26, 27, 27, 23, -15, 14, 21, -6, 0, 1, -19, -10, 28, -13, 13, 33, -2, 9, 7, -18, 6, 26, -16, 19, 23, -17, 5, 22, -8, 4, 34, -23, 14, 21, -19, 0, 30, -6, 3, 32, -22, 21, 17, -11, 4, 40, -6, 0, 24, -9, 19, 15, -10, 2, 15, -9, 4, 29, -18, 7, 13, -17, 8, 20, -17, 9, 30, -17, 12, 16, -4, 10, 9, -12, -5, 24, -15, 18, 17, -4, 8, 14, -11, 7, 34, -14, 20, 19, -1, 12, 43, 30, 8, 20, -12, 4, 9, -10, -13, 15, -6, 13, 23, -15, 15, 29, -1, 10, 15, 15, 12, 20, -15, 6, 6, -16, 1, 40, 30, 19, 28, -4, 0, 20, -10, 2, 8, 12, 8, 11, -2, 6, 27, 5, -5, 17, 17, 15, 17, -6, 6, 9, -6, -13, 30, 21, 21, 15, -2, 16, 19, -20, 3, 34, 23, 28, 27, -7, 7, 12, -12, 2, 34, 20, 26, 24, -10, 12, 12, -9, 4) longAttitude&lt;-data.frame(participant, drink, imagery, groups, attitude) </code></pre> <p>And here's the plot code:</p> <pre><code>library(ggplot2) attitudeInt &lt;- ggplot(longAttitude, aes(drink, attitude, colour = imagery)) attitudeInt + stat_summary(fun.y = mean, geom = "point") + stat_summary(fun.y = mean, geom = "line", aes(group = imagery)) + stat_summary(fun.data = mean_cl_boot, geom = "errorbar", width = 0.2) + labs(x = "Type of Drink", y = "Mean Attitude", colour = "Type of Imagery") </code></pre> <p>Isn't it the case that the part <code>stat_summary(fun.y = mean, geom="line", aes(group = imagery))</code> should draw exactly these connection lines?</p> <p>Thanks for your help.</p>

    1. COWorks for me. What version of R and ggplot2 are you using? Also, try restarting R into a clean session and trying again.

    3. CO@agstudy I'm still on 9.2.1, so that might be part of the problem.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
