dat | a data.frame contain regions and values |
---|---|
mapName | mapName for loading, eg. 'china', 'city', ... |
namevar | a formula show which feature is chosen for name variable |
valuevar | a formula show which feature is chosen for value variable |
palette | The colors or color function that values will be mapped to, see RColorBrewer::display.brewer.all() |
colorMethod | set one of the coloe mapping in c("numeric", "bin", "quantile", "Factor") |
na.color | The color to return for NA values. Note that na.color=NA is valid. |
popup | a character vector of the HTML content for the popups (you are recommended to escape the text using htmlEscape() for security reasons) |
stroke | whether to draw stroke along the path (e.g. the borders of polygons or circles) |
smoothFactor | how much to simplify the polyline on each zoom level (more means better performance and less accurate representation) |
weight | stroke width in pixels |
fillOpacity | fill opacity |
tileType | function to define tile like amap or leaflet::addTiles |
... | other paramter pass to the color mapping function |
