Download Poll Data

Saves the data of several polls as JSON files, exactly as published by POLITICO, e.g. to keep a snapshot or to work offline. The files can be read with popRead(code, dir = dir).

Usage

popDownload(dir, codes = NULL, overwrite = TRUE, quiet = FALSE)

Arguments

dir

Directory the files are written to, created if necessary.

codes

Codes of the polls to download, by default all polls listed by popGetInfo().

overwrite

Whether existing files should be replaced.

quiet

Whether progress messages should be suppressed.

Value

Invisibly a data.table with the columns code, file, status ("downloaded", "skipped" or "failed") and error.

Details

Requests are sent one after the other with a delay in between (see the pollofpolls.requestDelay option). A failed download does not stop the others, see the status column of the result.

Examples

if (FALSE) { # \dontrun{
popDownload('polls', codes = c('AT-parliament', 'DE-parliament'))
at = popRead('AT-parliament', dir = 'polls')

# everything
popDownload('polls')
} # }
