List and remove temporary pdfs — ls_temp

Using the functions in this package can lead to several pdf files cluttering your tempdir(). ls_temp_pdfs() lists them while rm_temp_pdfs() removes them. By default only the temporary pdf files created by this package are listed/removed.

Usage

ls_temp_pdfs(exclude = character(), fileext = "___pnpmisc.pdf")

rm_temp_pdfs(exclude = character(), fileext = "___pnpmisc.pdf")

Arguments

exclude: A character vector of filenames to exclude.
fileext: File extension of the temporary pdf files to list/remove. Defaults to ___pnpmisc.pdf, the file extension this package gives the temporary pdf files it creates. Use a more indiscriminate value such as ".pdf" to also list/remove pdf files in tempdir() created by other means.

Value

ls_temp_pdfs() returns a character vector. rm_temp_pdfs() returns invisible(NULL). As a side effect rm_temp_pdfs() deletes the listed files.

Examples

f1 <- pdf_create_blank()
f2 <- pdf_compress(f1)
f3 <- pdf_subset(f2, pages = 1L)
ls_temp_pdfs()
