In dataone: R Interface to the DataONE REST API

Get the checksum for the data object associated with the specified pid.

Description

A checksum is calculated for an object when it is uploaded to DataONE and is submitted with the object's system metadata. The 'getChecksum' method retrieves the checksum from the specified coordinating node

Usage

getChecksum(x, ...)

## S4 method for signature 'CNode'
getChecksum(x, pid, ...)

## S4 method for signature 'MNode'
getChecksum(x, pid, checksumAlgorithm = "SHA-256")

Arguments

x	The CNode instance from which the checksum will be retrieved
...	(Not yet used)
pid	The identifier of the object
checksumAlgorithm	The algorithm used to calculate the checksum. Default="SHA-256"

Value

character the checksum value, with the checksum algorithm as the attribute "algorithm"
