R传单:添加多边形时传递popupOptions. [英] R Leaflet: Passing popupOptions when adding Polygons.

问题描述

在addPolygons()中，有一个popup参数，就像addPopups()函数中的参数一样.区别(我认为)是，在addPolygons()中创建弹出窗口时，可以单击多边形内的任意位置以触发弹出窗口，但是如果使用addPopups()，则必须在单个c3和c6点上定义.

Within addPolygons() there is a popup parameter just like the one in the addPopups() function. The difference (I think) is that when the popup is created within addPolygons(), one can click anywhere within the polygon to trigger the popup, but if addPopups() is used, a single lng and lat point must be defined.

我想更改popupOptions()中的默认选项(maxWidth)之一，使用addPopups()时可以轻松完成，因为它包含参数options = popupOptions()，但是我不知道该怎么做使用addPolygons();在该函数中，options参数为options = pathOptions().

I want to change one of the default options (maxWidth) in popupOptions() which can easily be done when using addPopups() because it contains the parameter options = popupOptions() but I don't know how to do it when using addPolygons(); within that function the options parameter is options = pathOptions().

下面是传单文档中的可复制示例，其中添加了一个弹出窗口，我想增加maxWidth.

Below is a reproducible example from the leaflet documentation with a popup added that I'd like increase the maxWidth.

library(rgdal)

# From https://www.census.gov/geo/maps-data/data/cbf/cbf_state.html
states <- readOGR("shp/cb_2013_us_state_20m.shp",
  layer = "cb_2013_us_state_20m", verbose = FALSE)

neStates <- subset(states, states$STUSPS %in% c(
  "CT","ME","MA","NH","RI","VT","NY","NJ","PA"
))

leaflet(neStates) %>%
  addPolygons(
    stroke = FALSE, fillOpacity = 0.5, smoothFactor = 0.5,
    color = ~colorQuantile("YlOrRd", states$AWATER)(AWATER),
    popup="<b>Hello World</b>"
  )

推荐答案

您可以通过在addPloygons()块中的弹出窗口之后添加popupOptions()来简单地做到这一点，如下所示:

You can do this simply by adding popupOptions() after your popup in the addPloygons() block like so:

leaflet(neStates) %>%
    addPolygons(
        stroke = FALSE, fillOpacity = 0.5, smoothFactor = 0.5,
        color = ~colorQuantile("YlOrRd", states$AWATER)(AWATER),
        popup="<b>Hello World</b>"
        popupOptions = popupOptions(maxWidth ="100%", closeOnClick = TRUE)

)

以下是活页R上的PDF小插图中您可以放入popupOptions()列表中的所有内容的列表:

Here is the list from the PDF vignette on leaflet R of all the things you can drop in the popupOptions() list:

popupOptions(maxWidth = 300, minWidth = 50, maxHeight = NULL,
            autoPan = TRUE, keepInView = FALSE, closeButton = TRUE,
             zoomAnimation = TRUE, closeOnClick = NULL, className = "", ...)
