R version 0.7 demo

[darkblueb]

OSGeoLive 13 alpha1 includes R 3.4.4 and sf 0.7-3

Running the sample Jupyter notebook does work, but there is a missing R module called geojsonio

Edzer Pebesma says :

I have no clue where that comes from!

The fix I'd try first would be

install.packages("geojsonio")

but that might call for some external deps, like V8.

Can you link the source for the notebook you are trying? It does seems weird to use geojsonio, I would assume sf would use rgdal json drivers, and we can probably trace the use and swap out a line.

The cause is the IRKernel specifies that geojsonio package is used to display various things from sf objects. This is specific to Jupyter. Easiest solution is to add the geojsonio R library and it's dependencies. Not sure how much space this will take. This does include need to add the system V8 library.

sudo apt-get install libv8-dev

tested in nightly-build51, IRkernel 1.0 via CRAN

the same errors occur; display functions of ggplot2 work as expected
