ggpage features

Variable paragraph length

The ggpage package allows for variable length of paragraphs if the text doesn’t hold information regarding paragraphs. This is done by supplying the variable.paragraph.length argument in ggpage_build with a function that generate random natural numbers. Such as the rpois function.

library(magrittr)
library(dplyr)
library(ggpage)


book <- tinderbox %>%
  tidytext::unnest_tokens(text, text)

ggpage_build(book, para.fun = rpois, lambda = 75) %>%
  ggpage_plot()

ggpage_build(book, para.fun = rpois, lambda = 75) %>%
  ggpage_plot()

ggpage_build(book, para.fun = rpois, lambda = 500) %>%
  ggpage_plot()

ggpage_build(book, para.fun = rpois, lambda = 500) %>%
  ggpage_plot()

Show paper

With the newest update ggpage allows you to draw a rectangle around each “page”.

ggpage_build(tinderbox) %>%
  ggpage_plot(paper.show = TRUE)

It allows you use specify a color both as a constant,

ggpage_build(tinderbox) %>%
  ggpage_plot(paper.show = TRUE, paper.color = "pink")

or by a string of colors. In this case a faded rainbow.

ggpage_build(tinderbox) %>%
  ggpage_plot(paper.show = TRUE, paper.color = rainbow(9), paper.alpha = 0.3)

Show page number

It can be hard to see the order of the pages in the standard vizualization. However it is possible to add a page number in the sides or corners of each page.

directions <- c("top", "top-right", "right", "bottom-right", "bottom",
                "bottom-left", "left", "top-left")
ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[1])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[2])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[3])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[4])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[5])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[6])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[7])

ggpage_build(tinderbox) %>%
  ggpage_plot(page.number = directions[8])

Variable page length

The package also support a variable page length. This can be helpful when a collection of smaller texts are considered in the same vizualisation such as tweets.

tinderbox %>%
  mutate(short = ceiling(seq_len(nrow(tinderbox)) / 10)) %>%
  ggpage_build(page.col = "short", lpp = 10) %>%
  ggpage_plot()

Centering

ggpage now supports left, right and both-sided alignments.

ggpage_build(tinderbox, align = "right") %>%
  ggpage_plot()


ggpage_build(tinderbox, align = "both") %>%
  ggpage_plot()

Paragraph to line

Lastly for convience does ggpage include a way to transform a data.frame with paragraph tokens to a data.frame with line tokens.

nest_paragraphs(data = tinderbox_paragraph, input = text) %>%
  head()
#>                                                                               text
#> 1     A soldier came marching along the high road: "Left, right - left, right." He
#> 2  had his knapsack on his back, and a sword at his side; he had been to the wars,
#> 3 and was now returning home. As he walked on, he met a very frightful-looking old
#> 4  witch in the road. Her under-lip hung quite down on her breast, and she stopped
#> 5        and said, "Good evening, soldier; you have a very fine sword, and a large
#> 6    knapsack, and you are a real soldier; so you shall have as much money as ever

nest_paragraphs(tinderbox_paragraph, text, width = 40) %>%
  head()
#>                                     text
#> 1 A soldier came marching along the high
