A full list of R packages I have published are on my Github, but some notable ones are below.
Some are part of the cloudyR project, which has many packages useful for using R in the cloud. 
I concentrate on the Google cloud below, but be sure to check out the other packages if you’re looking to work with AWS or other cloud based services.
