The map I  created here was the main footprints through my 3-year life in Hualien.
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r library leaflet}
library(leaflet)
library(maptools)

Start creating a map

```{r creating maps for my dormitories}

Let's review dive sites and reef condition in Hualien

```{r new tile for diving sites}
ttile.D%>%
  addProviderTiles(provider = 'Stamen.TopOSMFeatures',
        providerTileOptions(opacity=1))
ttile.2<-ttile.D%>%leaflet::addMarkers(lng=dive$lng,
      lat=dive$lat,
      label=dive$site,
      icon= coralicon,
      popup=c('Best classroom for SCUBA training in Hualien','Low visibility with nice coral condition','High percentage of soft corals','High concentration of suspended particles','Unsuitable for newbie for the mountainous waves','Luxuriant corals inside the levee','Bare rocky bed covered by macroalgae','It is not recommanded to dive in harbor','Grandiose scenery with gorgonians and antipatherians'),
      clusterOptions = markerClusterOptions())

```

I'd like to mark where I've worked.
```{r create another tile about my jobs}

Now, I'd like to label several marine area that are unforgettable to me.
