R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

Including Plots

You can also embed plots, for example:

## 載入需要的套件：leaflet.extras
## Registered S3 method overwritten by 'geojsonsf':
##   method        from   
##   print.geojson geojson

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
