Feed: R-bloggers. Author: AbdulMajedRaja RS. One of the problems that we usually face with ggplot is that rearranging the bars in ascending or descending order. If that problem is solved using reorder() or fct_reorder(), the next problem is when we have facets and ordering bars within each facet. Recently I came acrosss this function reorder_within() from the package tidytext (Thanks to Julia Silge and Tyler Rinker – who created this solution originally) Example Code: library(tidyr) library(ggplot2) iris_gathered As you can see above, the bars in the last facet isn’t ordered properly. This is a problem you wouldn’t forget had you ... Read More

Managing usual dependencies of a package is clearly covered in R packages by Hadley Wickham. Typically, that would be the end of a tutorial or a post. However, teaching recently how to develop a package, I encountered a couple of super interesting and non-trivial questions that would not have a ... Read More

Feed: Recent Announcements. Today we are releasing a preview of Amplify iOS and Amplify Android, open source libraries that enable mobile developers to build scalable and secure cloud powered serverless applications. Developers can easily add capabilities such as Analytics, AI/ML, API (GraphQL and REST), DataStore, and Storage to their mobile applications using these Amplify libraries. Support for escape hatches in Amplify allows you to use the generated iOS and Android SDKs for additional use cases. The Amplify iOS and Android libraries are use case-centric, in contrast to the AWS service-centric Mobile SDKs, and provide a declarative interface that enables mobile developers ... Read More

Feed: SAS Blogs. Author: Sophia Rowland. R first appeared in 1993 and has gained a steady and fiercely loyal fan base. But as data sets become both longer and wider, storage and processing speeds become an issue. Having spent weeks whipping an extremely wide and messy data set into shape using only R, I am so grateful for Viya and not having to go through that again. SAS Viya is a cloud-enabled, in-memory analytics engine which allows for rapid analytics insights. Viya utilizes the SAS Cloud Analytics Services (CAS) to perform various actions and tasks. Best of all, CAS is ... Read More

Feed: Planet PostgreSQL. There is a less-talked-about improvement in PostgreSQL 12 which can greatly reduce the benign log entries. This patch is probably one of the smallest in PostgreSQL 12.The commit message says: Don't log incomplete startup packet if it's empty This will stop logging cases where, for example, a monitor opens a connection and immediately closes it. If the packet contains any data an incomplete packet will still be logged.

Feed: SAS Blogs. Author: Robert Allison. If you don't have a SAS/Graph license, then you're probably using the ODS Graphics 'sg' procedures that come with Base SAS to create your graphs and maps. And if you've tried plotting data on a map, you probably noticed that SGmap lets you overlay point-data on an OpenStreetmap, but you don't have any map polygons available to create choropleth maps (like the maps that are available in SAS/Graph's mapsgfk library). In this blog post, I share with you how to download some free polygon maps, and import them into SAS! Data Source The source ... Read More
