Using leaflet to create geographical mappings. NHS geographies as example.

• Code as: 02-geoplot-approach.R.

• ICB boundary downloaded from ONS Open Geography Geoportal. Others, such as Regions or Local Authorities, can also be sourced.

• Additional ICB information (for hover, colour-coding, labels, filtering) can be defined in ICS_master.xlsx. In this case, as an example, we sourced some additional population projection information and practice number information from NHS England allocations.

• Trust file trusts_master.xlsx should contain latitute and longitude. This can be geocoded from postcodes (provided in reference files, namely etr.csv and ect.csv), by using a library such as postcodesioR.

• Further trust information (for hover, colour-coding, labels, filtering) can be defined as additional columns in the same file.
