Onze flexdashboard omzetten naar Shiny
Laten we deze dashboard shiny maken!
Deze oefening maakt deel uit van de cursus
Dashboards bouwen met flexdashboard
Oefeninstructies
- Pas de YAML-header aan zodat dit een interactieve RMarkdown-document wordt.
- Genereer het dashboard en probeer verschillende regio’s te selecteren in de invoer-sidebar. Let op hoe het dashboard verandert.
Praktische interactieve oefening
