In ndphillips/ShinyPsych: An easy way to program psychology experiments using Shiny

Description

Check if a User is Allowed to Participate Given his Id

Usage

checkId(
  id,
  cntrlVals,
  location = "local",
  fileSep = ",",
  fileHeader = TRUE,
  dropDir = NULL,
  fileName = NULL,
  droptoken = NULL,
  idsVec = NULL,
  notAllowedId = "not allowed"
)

Arguments

id	string or numeric. The user id to check.
cntrlVals	list of reactive values.Controls the flow through the Experiment. Can be created with createCtrlList.
location	string. Where to get the reference database from. Must be one of "local", "dropbox" or "vector". "local" will load a txt or rds file. "dropbox" will load a csv file from the indicated dropbox account and "vector" assumes that you gave a vector of ids as input to idsVec.
fileSep	string. Passed to the read.table sep argument. Must match the separater used in the database file.
fileHeader	logical. Passed to the read.table header argument.
dropDir	string. The directory in the dropbox from which to read in the database. Must only be specified if location is set to "dropbox".
fileName	string. The database file-name, including path. Must be specified if location is one of "dropbox" or "local".
droptoken	string. The name of the rds file containing the access tokens of the dropbox account from which the data should be loaded. If file is outside the app directory full directory must be included.
idsVec	string. Vector of ids that are no longer allowed to participate. Must only be specified if location is set to "vector".
notAllowedId	string. The name (default is "not allowed") of the page that should be displayed in case the given id is occurring in the database.

Value

If id is also contained in database cntrlVals$page will be changed to notAllowedId. Does not have to be reassigned since it's a reactive value.
