A new RStudio addin to facilitate inserting tables in Rmarkdown documents

A new RStudio addin to facilitate inserting tables in Rmarkdown documents

In the last months, I started increasingly using Rmd documents for preparing scientific reports, blog posts, etcetera. While I really like the flexibility offered by the system, one thing that I thought could be improved is the support for easily inserting tables. So, “inspired” also by the recent addition of the excellent insert image addin in blogdown, I decided...

Automatically importing publications from bibtex to a hugo-academic blog

Automatically importing publications from bibtex to a hugo-academic blog

The problem I am in the process of migrating my (rather ugly) small blog from “Bloggers” to blogdown and, as several others, I choose to use the hugo-academic theme due to its good looks, simplicity, and “focus” towards researchers. One nice feature of hugo-academic is that it includes out-of-the-box a “Publications” section, allowing researchers to easily create a list of their...

He was seeking efficient solutions to identify all points falling within a maximum distance of xx meters with respect to each single point in a spatial points dataset. If you have a look at the thread, you will see that a simple solution based on creating...

Building a website with `pkgdown`: a short guide

Building a website with `pkgdown`: a short guide

As promised in my last post, here is a short guide with some tips and tricks for building a documentation website for an R package using pkgdown. In the end, this guide ended up way longer than I was expecting, but I hope you’ll find it useful, although it often replicates information already available in pkgdown documentation !

The new MODIStsp website (based on pkgdown) is online !

The MODIStsp website, which lay abandoned since several months on github pages, recently underwent a major overhaul thanks to pkgdown. The new site is now available at http://lbusett.github.io/MODIStsp/ We hope that the revised website will allow to navigate MODIStsp-related material much more easily than either github or the standard CRAN documentation, and will therefore help users in better and more easily exploiting MODIStsp functionality. The...
