Adding a Piece of Flair
Earlier in this chapter, we used addSearchOSM()
to find the middle of the US. To search for markers, rather than locations, we can use the addSearchFeatures()
function. addSearchFeatures()
will add a search box that you can use to find markers in the group(s) passed to the targetGroups
argument. For example, to search our map for public colleges we could use the following code.
m4 %>%
addSearchFeatures(
targetGroups = 'Public',
options = searchFeaturesOptions(zoom = 10))
The m4
map and the leaflet.extras
package have been loaded for you.
This exercise is part of the course
Interactive Maps with leaflet in R
Exercise instructions
- Use the
addSearchFeatures()
function to make colleges in all sectors searchable. - Set the search zoom level to 18.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Make each sector of colleges searchable
m4_search <- m4 %>%
addSearchFeatures(
targetGroups = ___(___, ___, ___),
# Set the search zoom level to 18
options = searchFeaturesOptions(___ = ___))
# Try searching the map for a college
