R Client for the Alexa Web Information Services API

Use the Alexa Web Information Service API to find information about domains, including the kind of content that they carry, how popular are they---rank and traffic history, sites linking to them, among other things.

To use the package, you will need an AWS account and 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.

By default, all cloudyr packages look for the access key ID and secret access key in environment variables. You can also use this to specify a default region. For example:

Sys.setenv("AWS_ACCESS_KEY_ID" = "mykey",
           "AWS_SECRET_ACCESS_KEY" = "mysecretkey",
           "AWS_DEFAULT_REGION" = "us-east-1")

These can alternatively be set on the command line or via an Renviron.site or .Renviron file (see here for instructions).
