P <- p + labs(subtitle = chi_subtitle(jmv::contTables(df2, rows = 'col1', cols = 'col2', phiCra = TRUE),Īs you can see, it works fine for some conditions, but not for other. P <- p + facet_wrap(condition, labeller = "label_both") # reorder the category factor levels to order the legendĭf] % dplyr::select(condition, main) # if it doesn't work, try toying with the formula for the label_pos to get the desired result value <- 0. # label_pos is a tricky variable to define.the one here will work fine in most, but not all, cases Here’s a video walkthrough with the code used in the video below that. In this recipe, we will learn how to add the percentage values in addition to the names of slices, thus making them more readable. In this article, we are going to see how to create a pie chart with percentage labels using ggplot2 in R Programming Language. # the chi-square test presented.if not entered, the default will be "Chi-square test"ĭplyr::mutate(perc = counts / sum(counts)) %>%ĭplyr::mutate(label_pos = sum(perc) - cumsum(perc) + perc / 2,
# effect is the text label that needs to be entered to denote which interaction effect is being investigated in # custom function to write results from chi-square test into subtitle for the plot
