Installing RStudio & Shiny Servers
I did a remote install of Ubuntu Server today. This was somewhat novel because it’s the first time that I have not had physical access to the machine I was installing on. The server install went very smoothly indeed. The next tasks were to install RStudio Server and Shiny Server. The installation process for each of these is well documented on ...

Survey Raking: An Illustration
Analysing survey data can be tricky. There’s often a mismatch between the characteristics of the survey respondents and and those of the general population. If the discrepancies are not accounted for then the survey results can (and generally will!) be misleading. A common approach to this problem is to weight the individual survey responses so...

Where does .Renviron live on Citrix?
At one of my clients I run RStudio under Citrix in order to have access to their data. For the most part this works fine. However, every time I visit them I spend the first few minutes of my day installing packages because my environment does not seem to be persisted from one session to the next. I finally had a gap and decided to fix the problem...

Docker Images for R: r-base versus r-apt
I need to deploy a Plumber API in a Docker container. The API has some R package dependencies which need to be baked into the Docker image. There are a few options for the base image: r-base tidyverse or r-apt. The first option, r-base, would require building the dependencies from source, a somewhat time consuming operation. The last option, r-...

Integrating Qlik Sense and R
Components Qlik Sense is a tool for exploratory data analysis and visualisation. It’s powerful and versatile. It’s can, however, be significantly enhanced by interfacing with R. Qlik Sense does not currently integrate directly with R. However, it’s not too tricky to get the two systems talking to each other. We’ll need two things to make ...

Setting up an R Admin Group
When I set up an R server for clients they often want to be able to install packages so that all users on the machine have access to them. This requires them to be able to install the packages onto the root filesystem rather that under their individual home directories. It would be easy enough to give them su access, but this is a risky approach....

We’ve had the most experience with the first two, both of which are really solid packa...
