AWS.Lambda

This an R client to interact with the AWS Lambda Service, including wrapper functions around the Lambda Java client to invoke functions on that service.

Installation

You can easily install the most recent development version of the R package:

remotes::install_github('nfultz/AWR.Lambda')

This R package relies on the jar files bundled with the AWR package.

What is it good for?

Currently, only the most important features are supported:

• you can invoke a lambda function:

> AWR.Lambda::invoke("myFunctionName",  list(key3="value3", key2="value2",key1="value1"))
[1] "Hello from Lambda"

What if I want to do other cool things with Lambda and R?

Writing wrapper functions around the Java SDK is very easy. Please open a ticket on the feature request, or even better, submit a pull request :)

It doesn't work here!

To be able to use this package, you need to have an AWS account. If you do not have one already, you can register for free at Amazon, although you may be billed for using lambda functions .

Once you have an AWS account, make sure your default AWS Credentials are available via the DefaultAWSCredentialsProviderChain . In short, you either provide a default credential profiles file at ~/.aws/credentials, use the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables or if using AWR.Lambda on AWS, you can also rely on the EC2 instance profile credentials or ECS Task Role as well.
