    It's tibbletime v0.0.2: Time-Aware Tibbles, New Functions, Weather Analysis and More

    Written by Davis Vaughan on October 8, 2017

    Today we are introducing tibbletime v0.0.2, and we’ve got a ton of new features in store for you. We have functions for converting to flexible time periods with the ~period formula~ and making/calculating custom rolling functions with rollify() (plus a bunch more new functionality!). We’ll take the new functionality for a spin with some weather data (from the weatherData package). However, the new tools make tibbletime useful in a number of broad applications such as forecasting, financial analysis, business analysis and more! We truly view tibbletime as the next phase of time series analysis in the tidyverse. If you like what we do, please connect with us on social media to stay up on the latest Business Science news, events and information!

    It's tibbletime: Time-Aware Tibbles

    Written by Davis Vaughan on September 7, 2017

    We are very excited to announce the initial release of our newest R package, tibbletime. As evident from the name, tibbletime is built on top of the tibble package (and more generally on top of the tidyverse) with the main purpose of being able to create time-aware tibbles through a one-time specification of an “index” column (a column containing timestamp information). There are a ton of useful time functions that we can now use such as time_filter(), time_summarize(), tmap(), as_period() and time_collapse(). We’ll walk through the basics in this post.

    alphavantager: An R interface to the Free Alpha Vantage Financial Data API

    Written by Matt Dancho on September 3, 2017

    We’re excited to announce the alphavantager package, a lightweight R interface to the Alpha Vantage API! Alpha Vantage is a FREE API for retreiving real-time and historical financial data. It’s very easy to use, and, with the recent glitch with the Yahoo Finance API, Alpha Vantage is a solid alternative for retrieving financial data for FREE! It’s definitely worth checking out if you are interested in financial analysis. We’ll go through the alphavantager R interface in this post to show you how easy it is to get real-time and historical financial data. In the near future, we have plans to incorporate the alphavantager into tidyquant to enable scaling from one equity to many.
