In my previous post – HexJSON HTMLWidget for R, Part 1 – I described a first attempt at an HTMLwidget for displaying hexJSON maps using
I had another play today and added a few extra features, including the ability to:
- add a grid (as demonstrated in the original
- modify the default colour of data and grid hexes,
- set the data hex colour via a
colattribute defined on a hexJSON hex, and
- set the data hex label via a
labelattribute defined on a hexJSON hex.
We can now also pass in the path to a hexJSON file, rather than just the hexJSON object:
Here’s the example hexJSON file:
And here’s an example of the default grid colour and a custom text colour :
I’ve also tried to separate out the code changes as separate commits for each feature update: code checkins. For example, here’s where I added the original colour handling.
I’ve also had a go at putting some docs in place, generated using
roxygen2 called from inside the widget code folder with
devtools::document(). (The widget itself gets rebuilt by running the command
Next up – some routines to annotate a base hexJSON file with data to colour and label the hexes. (I’m also wondering if I should support the ability to specify arbitrary hexJSON hex attribute names for label text (
label) and hex colour (
col), or whether to keep those names as a fixed requirement?) See what I came up with here: HexJSON HTMLWidget for R, Part 3.
