facet_wrap_paginate: Split facet_wrap over multiple plots


This extension to facet_wrap will allow you to split a facetted plot over multiple pages. You define a number of rows and columns per page as well as the page number to plot, and the function will automatically only plot the correct panels. Usually this will be put in a loop to render all pages one by one.


facet_wrap_paginate(facets, nrow = NULL, ncol = NULL, scales = "fixed", shrink = TRUE, labeller = "label_value", as.table = TRUE, switch = NULL, drop = TRUE, dir = "h", strip.position = "top", page = 1)


Either a formula or character vector. Use either a one sided formula, ~a + b, or a character vector, c("a", "b").
Number of rows and columns.
Number of rows and columns
should Scales be fixed ("fixed", the default), free ("free"), or free in one dimension ("free_x", "free_y").
If TRUE, will shrink scales to fit output of statistics, not raw data. If FALSE, will be range of raw data before statistical summary.
A function that takes one data frame of labels and returns a list or data frame of character vectors. Each input column corresponds to one factor. Thus there will be more than one with formulae of the type ~cyl + am. Each output column gets displayed as one separate line in the strip label. This function should inherit from the "labeller" S3 class for compatibility with labeller(). See label_value for more details and pointers to other options.
If TRUE, the default, the facets are laid out like a table with highest values at the bottom-right. If FALSE, the facets are laid out like a plot with the highest value at the top-right.
By default, the labels are displayed on the top and right of the plot. If "x", the top labels will be displayed to the bottom. If "y", the right-hand side labels will be displayed to the left. Can also be set to "both".
If TRUE, the default, all factor levels not used in the data will automatically be dropped. If FALSE, all factor levels will be shown, regardless of whether or not they appear in the data.
Direction: either "h" for horizontal, the default, or "v", for vertical.
By default, the labels are displayed on the top of the plot. Using strip.position it is possible to place the labels on either of the four sides by setting strip.position = c("top", "bottom", "left", "right")
The page to draw

Run this code
# Calculate the number of pages with 9 panels per page
n_pages <- ceiling(
  length(levels(diamonds$cut)) * length(levels(diamonds$clarity)) / 9

# Draw each page
for (i in seq_len(n_pages)) {
  ggplot(diamonds) +
