List all surveys available for download

Usage

list_surveys(
  directory = contactsurveys_dir(),
  overwrite = FALSE,
  verbose = TRUE
)

directory: Directory of where to save survey files. The default value is to use the directory for your system using contactsurveys_dir(), which uses tools::R_user_dir(). This effectively caches the data. You can specify your own directory, or set an environment variable, CONTACTSURVEYS_HOME, see Sys.setenv() or Renviron for more detail. If this argument is set to something other than contactsurveys_dir(), a warning is issued to discourage unnecessary downloads outside the persistent cache.
overwrite: If files should be overwritten if they already exist. Default FALSE
verbose: Whether downloads should be echoed to output. Default TRUE.

data.table with columns: date_added, title, creator, url
