Opal login

Log in Opal(s). Different login strategies are possible: (1) by providing username/password, or (2) by providing username/password and a one-time password code (TOPT) when user has activated two-factor authentication, or (3) by providing a personal access token (PAT), or (4) by providing a key pair in PEM format.

opal.login(
  username = getOption("opal.username"),
  password = getOption("opal.password"),
  token = getOption("opal.token"),
  url = getOption("opal.url"),
  opts = getOption("opal.opts", list()),
  profile = getOption("opal.profile"),
  restore = NULL
)

Arguments

username: User name in opal(s). Can be provided by "opal.username" option.
password: User password in opal(s). Can be provided by "opal.password" option.
token: Personal access token (since opal 2.15). Only effective if the username or the password is NULL or empty. Can be provided by "opal.token" option.
url: Opal url or list of opal urls. Can be provided by "opal.url" option. Secure http (https) connection is required.
opts: Curl options as described by httr (call httr::httr_options() for details). Can be provided by "opal.opts" option.
profile: R server profile name. This will drive the R server in which a R session will be created. If no remote R session is needed (because Opal specific operations are done), this parameter does not need to be provided. Otherwise, if missing, the default R server profile will be applied ('default'). See also opal.profiles.
restore: Workspace ID to be restored (see also opal.logout)

Value

A opal object or a list of opal objects.
