To use the package, you will need an AWS account and to enter your credentials into R. Your keypair can be generated on the IAM Management Console under the heading Access Keys. Note that you only have access to your secret key once. After it is generated, you need to save it in a secure location. New keypairs can be generated at any time if yours has been lost, stolen, or forgotten. The aws.iam package profiles tools for working with IAM, including creating roles, users, groups, and credentials programmatically; it is not needed to use IAM credentials. And you can begin performing operations on the queue. The most important of these are send_msg() (to put a message into the queue), receive_msg() (to retrieve one or more messages from the queue), and delete_msg() (to delete a message once it is no longer needed in the queue).
