ggpage is a package to create pagestyled visualizations of text based data. It uses ggplot2 and final returns are ggplot2 objects.
In this new version I have worked to include a lot of use cases that wasn’t available in the first version. These new elements are previewed in the vignette.
You can install the released version of ggpage from CRAN with:
or you can install the developmental version of ggpage from github with:
# install.packages("devtools") devtools::install_github("EmilHvitfeldt/ggpage")
The package includes The Tinder-box by H.C. Andersen for examples.

The basic workflow with ggpage is using either
ggpage_quickfor a quick one function call plot or,
ggpage_plotto do analysis (NLP for example) before the final plot is produced.
For a simple demonstration we apply
ggpage_quick to our
object. It is important that the data.frame that is used have the text
in a column named “text”.
ggpage_quick(tinderbox) #> Warning: replacing previous import 'dplyr::vars' by 'rlang::vars' when #> loading 'tidytext'
# Also pipeable # tinderbox %>% ggpage_quick()
The same result would be achieved by using
tinderbox %>% ggpage_build() %>% ggpage_plot()
But this approach allows us to introduce more code between
ggpage_plot giving us multiple more ways to enhance
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")
