writing out CSV, TSV and JSON files.make_thumbnails() and split_pdf() now use
tempdir() as the default output directory.extract_ functions get copy argument for
copying original local files to R session’s temporary directory.method argument is changed to output in
extract_tables().method argument reflects method of extraction as in
Tabula command-line Java utility.extract_text() accepts area as
argument.widget in
locate_areas() to control which widget is used in locating
areas.try_area_full()
introduced by changes in8.locate_areas() interface to use a
Shiny gadget when working within RStudio, or otherwise rely on the full
functionality interface (based on graphics device events) or reduced
functionality interface (relying on locator()). (#8)locate_areas() interface to rely
on graphics device event handling where possible. This may behave
differently across platforms or in RStudio. (#8)extract_tables() such that when no
tables are found, an empty list is returned (for method
values with list response structures). (h/t Lincoln Mullen)split_pdfs() and make_thumbnails() gain an
outdir argument to specify where to save the output. The
file numbering of output files is also now zero-padded.merge_pdfs() has been fixed.stop_logging() is called when the package is attached
to the search path.get_page_dims() earns a doc argument and
argument order in get_n_pages() is reversed.extract_areas() by
downloading PDF to temporary directory.split_pdf() and

into individual image files.get_page_dims(), to extract page
dimensions.area argument when
length(area) == 1 & length(pages) > 1. (#5, #6)area argument. (#5,
#6)spreadsheet argument, a la Tabula itself.area and columns

They may not be fully stable and should be used with caution. We make no claims about them.
