Description Usage Arguments Details Value Author(s) References Examples

Retrieves the amount of money (in US Dollars) in your MTurk account. SufficientFunds provides a wrapper that checks whether your account has sufficient funds based upon specified characters of your HIT.

AccountBalance(verbose = getOption('MTurkR.verbose', TRUE), ...)

SufficientFunds(amount = NULL, assignments = NULL, hits = NULL, 
                bonus.ct = NULL, bonus.amount = NULL, masters = FALSE, 
                turkfee = 0.2, turkmin = 0.01, mastersfee = 0.05, ...)

`amount`	Intended per-assignment payment amount.
`assignments`	Number of intended assignments (per HIT, if multiple HITs).
`hits`	Number of HITs.
`bonus.ct`	Number of intended bonuses.
`bonus.amount`	Amount of each bonus.
`masters`	A logical indicating whether MTurk Masters will be used. Default is `FALSE`.
`turkfee`	Amazon's fee as percentage of payments. Default is 20-percent (as 0.20). Note, however, that MTurk charges an additional 20-percent if the number of `assignments` is greater than or equal to 10. This is factored in automatically
`turkmin`	Amazon's minimum per-assignment fee. Default is $0.01.
`mastersfee`	Amazon's additional charge for use of MTurk Masters. Default is 5-percent (as 0.05).
`verbose`	Optionally print the results of the API request to the standard output. Default is taken from `getOption('MTurkR.verbose', TRUE)`.
`...`	Additional arguments passed to `request`.

AccountBalance takes no substantive arguments. SufficientFunds is a wrapper for AccountBalance that accepts as inputs information about intended payments and bonuses to check whether your account has sufficient funds. If sandbox=TRUE, AccountBalance always returns “$10,000.00”.

accountbalance() and getbalance() are aliases for AccountBalance.

Return value is an object of class “MTurkResponse”, including an additional character string (balance) containing the balance of the account in US Dollars. Note: object is returned invisibly.
