Project Environments • renv
The renv package helps you create reproducible environments for your R projects. Use renv to make your R projects more:

Isolated: Installing a new or updated package for one project won’t break your other projects, and vice versa. That’s because renv gives each project its own private package library.

Portable: Easily transport your projects from one computer to another, even across different platforms. renv makes it easy to install the packages your project depends on.

Reproducible: renv records the exact package versions you depend on, and ensures those exact versions are the ones that get installed wherever you go.

Twitter's new R package for anomaly detection
For Twitter, finding anomalies — sudden spikes or dips — in a time series is important to keep the microblogging service running smoothly. A sudden spike in shared photos may signify an "trending" event, whereas a sudden dip in posts might represent a failure in one of the back-end services that needs to be addressed. To detect such anomalies, the engineering team at Twitter created the AnomalyDetection R package, which they recently released as open source. (Late last year Twitter released a separate but related R package to detect "breakouts" in time series.) Finding spikes and dips is relatively easy...

plyr is a set of tools for a common set of problems: you need to split up a big data structure into homogeneous pieces, apply a function to each piece and then combine all the results back together. For example, you might want to:

fit the same model to subsets of a data frame
quickly calculate summary statistics for each group
perform group-wise transformations like scaling or standardising
