We're RStudio Trainers!

We’re RStudio Trainers! Big news. RStudio recently started certifying trainers in three areas: the tidyverse, Shiny and teaching. To be certified to teach a topic you have to pass the exam for that topic and the teaching exam. Even bigger news. Four of your lovely Jumping Rivers trainers are now certified to teach at least one topic!

Timing hash functions with the bench package

This blog post has two goals Investigate the {bench} package for timing R functions Consequently explore the different algorithms in the {digest} package using {bench} What is {digest}? The {digest} package provides a hash function to summarise R objects. Standard hashes are available, such as md5, crc32, sha-1, and sha-256. The key function in the package is digest() that applies a cryptographical hash function to arbitrary R objects. By default, the objects are internally serialized using md5.

Thoughts on SatRday Newcastle

Earlier this month I attended the inaugural SatRday Newcastle. This was my first time attending a SatRday event, and I had a really enjoyable day. The event was sponsored by Newcastle University, Sage, RStudio and Jumping Rivers. There were over 100 attendees from across the U.K. Most attendees were from industry, although there were also a couple of academics present. There were also lots of R-Ladies, including women from the newly formed R-Ladies Newcastle, who are launching next month.

R Packages: Are we too trusting?

One of the great things about R, is the myriad of packages. Packages are typically installed via CRAN Bioconductor GitHub But how often do we think about what we are installing? Do we pay attention or just install when something looks neat? Do we think about security or just take it that everything is secure? In this post, we conducted a little nefarious experiment to see if people pay attention to what they install.

{benchmarkme}: new version

When discussing how to speed up slow R code, my first question is what is your computer spec? It’s always surprised me that people are wondering why analysing big data is slow, yet they are using a five-year-old cheap laptop. Spending a few thousand pounds would often make their problems disappear. To quantify the impact of the CPU on analysis, I created the package {benchmarkme}. The aim of this package is to provide a set of benchmarks routines and data from past runs.

R Conference Costs v2.0

R conference Costs Last year we gave you a price break down of some of the most popular R conferences around the globe for 2017. We’re going to do it again for 2018. Remember, you can get up-to-date information on upcoming conferences via our GitHub page. It’s important to note that these costs are the prices of an industry ticket for the conference only. If you caught the tickets on early bird and are an academic/student you could see these prices fall by over 50% in some cases.
