Convert documents to pdf
Convert documents to pdf using Libre Office. It supports very well "Microsoft PowerPoint" to PDF. "Microsoft Word" can also be converted but some Word features are not supported such as sections.
Windows users must be warned the program is slow on your platform. Performances are not excellent but fast enough on other platform.
to_pdf(

output = gsub("\\.[[:alnum:]]+$", ".pdf", input),
use_docx2pdf = FALSE,
UserInstallation = NULL
)input, output |
file input and optional file output. If output file is not provided, the value will be the value of input file with extension "pdf". |
use_docx2pdf |
if TRUE (and if 'Microsoft Word' executable can be found as well as 'docx2pdf'), docx2pdf will be used to convert 'Word' documents to PDF. This makes it possible to have a PDF identical to the 'Word' display whereas with 'LibreOffice', this is not always the case. |
UserInstallation |
use this value to set a non-default user profile path for "LibreOffice". If not provided a temporary dir is created. It makes possibles to use more than a single session of "LibreOffice." |
the name of the produced pdf (the same value as output),
invisibly.
On some Ubuntu platforms, 'LibreOffice' require to add in
the environment variable LD_LIBRARY_PATH the following path:
/usr/lib/libreoffice/program (you should see the message
"libreglo.so cannot open shared object file" if it is the case). This
can be done with R
command Sys.setenv(LD_LIBRARY_PATH = "/usr/lib/libreoffice/program/")
library(locatexec)
if (exec_available("libreoffice") && check_libreoffice_export()) {
out_pptx <- tempfile(fileext = ".pdf")
file <- system.file(package = "doconv",
"doc-examples/example.pptx")
to_pdf(input = file, output = out_pptx)
out_docx <- tempfile(fileext = ".pdf")
file <- system.file(package = "doconv",
"doc-examples/example.docx")
to_pdf(input = file, output = out_docx)
