epub_head R Documentation
Preview the first n characters
Description
Preview the first n characters of each EPUB e-book section.
Usage
epub_head(x, n = 50)
Arguments
x
a data frame returned by epub or a character string giving the EPUB filename(s).
n
integer, first n characters to retain from each e-book section.
Details
This function returns a simplified data frame of only the unnested section and text columns of a data frame returned by epub, with the text included only up to the first n characters.
This is useful for previewing the opening text of each e-book section to inspect for possible useful regular expression patterns to use for text-based section identification.
For example, an e-book may not have meaningful section IDs that distinguish one type of book section from another, such as chapters from non-chapter sections,
but the text itself may contain this information at or near the start of a section.
Value
a data frame.

epub_cat
Examples
file <- system.file("dracula.epub", package = "epubr")
epub_head(file)
