问题
when I plot via pdf() in R, I would like to set the meta data for the PDF: title, author, keywords, subject. The default for the title seems to be "R Graphics Output".
How can I specify the meta data?
回答1:
You may set the document's title by passing an appropriate title arg to the pdf() function. For other metadata, refer to this SO Q&A in which the usage of external tools (like pdftk or exiftool) is recommended, see this Q&A at AskUbuntu.
