Using Shinydashboard in an learning analytics setting.
Today I just finished a report for a course I organized at my university. Normally I would just use Knitr and generate a one page html document, but it just happened I’m on holiday and have some time to spare.
So I decided to experiment a bit with the shinydashboard package. My opinion? Only Powerpoint is easier to use. I deployed the final app on both Shinyapps and my own Shiny Server (hosted at Amazon’s EC2 servers).
They work perfectly although I had some trouble getting it to work at my own server. The error: ”ReadItem: unknown type 0, perhaps written by later version of R” was rather cryptic. However, in the end it proved to be a small thing: you should only copy the R.files and any other supporting files. Not the .RData and/or .Rhistory files.
Took me some hours to figure that out. But hey, all learning comes at a cost (that’s what I always tell my students). At least now all my systems have the newest updates and are running like champions.
