ggpage
ggpage is a package to create pagestyled visualizations of text based data. It uses ggplot2 and final returns are ggplot2 objects.
Installation
You can install ggpage from github with:
# install.packages("devtools")
devtools::install_github("EmilHvitfeldt/ggpage")Example
The package includes The Tinder-box by H.C. Andersen for examples.
library(ggpage)
head(tinderbox, 10)

-
ggpage_quickfor a quick one function call plot or, - combining
ggpage_buildandggpage_plotto do analysis (NLP for example) before the final plot is produced.
For a simple demontration we apply ggpage_quick to our tinderbox object.
ggpage_quick(tinderbox)
# Also pipeable
# tinderbox %>% ggpage_quick()The same result would be achived by using
tinderbox %>%
ggpage_build() %>%
ggpage_plot()But this approach allows us to introduce more code between ggpage_build and ggpage_plot giving us multiple more ways to enhance the plots
tinderbox %>%
ggpage_build() %>%
mutate(long_word = stringr::str_length(word) > 8) %>%
ggpage_plot(aes(fill = long_word)) +
labs(title = "Longer words throughout The Tinder-box") +
scale_fill_manual(values = c("grey70", "blue"),
labels = c("8 or less", "9 or more"),
name = "Word length")
And it will nicely with other tidyverse packages
library(ggpage)
library(purrr)
library(gganimate)
prebuild <- tinderbox %>%
ggpage_build() %>%
left_join(get_sentiments("afinn"), by = "word")
midbuild <- map_df(.x = 0:50 * 10 + 1,
~ prebuild %>%
mutate(score = ifelse(is.na(score), 0, score),
score_smooth = zoo::rollmean(score, .x, 0),
score_smooth = score_smooth / max(score_smooth),
rolls = .x))
p <- midbuild %>%
ggpage_plot(aes(fill = score_smooth, frame = rolls)) +
scale_fill_gradient2(low = "red", high = "blue", mid = "grey", midpoint = 0) +
guides(fill = "none") +
labs(title = "Smoothed sentiment of The Tinder-box, rolling average of")
gganimate(p, interval = .2)
