We offer a separate workshop on mapping in R.  Please see our [*Mapping with R* guide](/map/) for more information.  

```{r loadPackages, echo=TRUE, message=FALSE, warning=FALSE}
library(tidyverse)

## GIS Mapping

Introducing the `library(leaflet)` we use 4 lines of code to make an interactive map.^[[5 Visualizations in 5 Minutes](http://www.computerworld.com/article/2893271/business-intelligence/5-data-visualizations-in-5-minutes-each-in-5-lines-or-less-of-r.html). ComputerWorld.com by Sharon Machlis]

### Filter Data to NC
```{r filter-dataset}
starbucksNC <- starbucks  %>% 
  filter(State == "NC")
```


### Make the Map
```{r makemap}
leaflet() %>% 
  addTiles() %>% 
  setView(-78.8310, 35.9867, zoom = 10) %>% 
  addMarkers(data = starbucksNC, lat = ~ Latitude, lng = ~ Longitude, popup = starbucksNC$Name)
```
