Building a Better Pop-up

With the paste0() function and a few html tags, we can customize our popups. paste0() converts its arguments to characters and combines them into a single string without separating the arguments.

addCircleMarkers(popup = ~paste0(name,
                                 "<br/>",
                                 sector_label))

We can use the <br/> tag to create a line break to have each element appear on a separate line.

To distinguish different data elements, we can make the name of each college italics by wrapping the name variable in `

addCircleMarkers(popup = ~paste0("<i>",
                                 name,
                                 "</i>", 
                                 "<br/>", 
                                 sector_label))
