In the just-released version 4.4.0 of Oracle Big Data Lite VM, as in the previous one (126.96.36.199), there is a rather large number of additional R packages to be installed by the provided script install_additional_packages.sh, i.e. 28 packages without counting their dependencies (the respective number in version 4.2.1 was only 10). Unfortunately, what has also changed is the form...
There is a saying that there are two groups of people: those who are already doing backups and those who will. So, how this is linked with reproducible research and R? If your work is to analyze data then you often face a need to restore/recreate/update results that you have generated some time ago. You … Czytaj dalej...

One of our readers commented on our mode exercises post: “What real world tasks are you using mode to solve?” I think it’s an interesting question, from a somewhat larger perspective.

Thinking about reproducible research and learning the important
tools is what improved my work more than anything.

The knitr/R markdown system is a great way to organize reports and analyses. However, the built-in ones (that come with RStudio/the rmarkdown package) rely on Bootstrap and also use jQuery. There’s nothing wrong with that, but the generated standalone HTML documents (which are a great way to distribute reports) don’t really need all that cruft
by Joseph Rickert A frequent question that we get here at Microsoft about MRO (Microsoft R Open) is: can be used with RStudio? The short answer is absolutely yes! In fact, more than just being compatible, MRO is the perfect complement for the RStudio environment. MRO is a downstream distribution of open source R that supports multiple operating systems...
