uspto_download(guid, outDir = tempdir(), type = "US-PGPUB",
  cores = detectCores() - 2, compress = TRUE, load = TRUE,
  verbose = FALSE)

Arguments

guid

outDir

Path to a directory in which to save each individual document. If not specified, these are saved to a temporary directory.

type

A vector the same length as guid (repeated as necessary), indicating the source database of the guid. Defaults to US-PGPUB for every ID.

Number of CPU cores to split requests across.

compress
