Feed: R-bloggers. Author: Keith Goldfeld. I was recently contacted to see if simstudy can create a data set of correlated outcomes that are measured over time, but at different intervals for each individual. The quick answer is there is no specific function to do this. However, if you are willing to assume an “exchangeable” correlation structure, where measurements far apart in time are just as correlated as measurements taken close together, then you could just generate individual-level random effects (intercepts and/or slopes) and pretty much call it a day. Unfortunately, the researcher had something more challenging in mind: he wanted ... Read More

Feed: AWS Big Data Blog. In this post, we talk about designing a cloud-native data warehouse as a replacement for our legacy data warehouse built on a relational database.At the beginning of the design process, the simplest solution appeared to be a straightforward lift-and-shift migration from one relational database to another. However, we decided to step back and focus first on what we really needed out of a data warehouse. We started looking at how we could decouple our legacy Oracle database into smaller microservices, using the right tool for the right job. Our process wasn’t just about using the ... Read More

Feed: What's New. Amazon Redshift's sophisticated query planner uses a table's statistical metadata to choose the optimal query execution plan for better query performance. The analyze operation generates or updates the table statistics. With this update, you no longer need to explicitly run the ANALYZE command. If you do run it as part of your extract, transform, and load (ETL) workflow, automatic analyze skips tables with up-to-date statistics. Similarly, an explicit ANALYZE skips tables with up-to-date table statistics. For more information, see Automatic Analyze in the Amazon Redshift Database Developer Guide. Automatic Analyze is now available with the release version ... Read More

Feed: R-bloggers. Author: Gavin L. Simpson. Recently I’ve been preparing my gratia package for submission to CRAN. During my pre-flight testing I noticed an issue under Windows checking the examples in the package against the reference output I generated on linux. In the latest release of the tibble package, the way tibbles are printed has changed subtly and in a way that leads to cross-platform differences. As I write this, tibbles with more than a set number of rows are printed in a truncated form, showing only the first 10 rows of data. In such cases, a final line is ... Read More

Feed: R-bloggers. Author: dan. WIND SPEEDS UP HEAT LOSS Twenty years ago, a German colleague asked me what the deal was with wind chill. I guess they didn’t have it in Germany. I explained it was an attempt to communicate how it feels when there is a low temperature combined with wind.  But my colleague wanted to know how they get the values in charts like these: If you look closely at the first chart, it gives the formula for wind chill. It looks pretty hairy but it’s just a function of two things: wind speed and temperature. The windchill ... Read More

Image credit: Results from the 2018 RStudio Learning R Survey, shared by Carl Howe at RStudio Conf 2019 Y’all if I had just one takeaway from R Studio Conference 2019, it’s that we are a friendly and tight knit community! Virtually and in person, we look out for each other. This past week, the FOMO was real, both from those unable to attend the conference and those who came. There were so many great sessions and such excellent information floating around that it was hard to keep up. In this blog, my focus is to ... Read More
