悬停在 R 中的传单时弹出?
Popup when hover with leaflet in R?
我的传单地图看起来像这样:
library(sp)
library(leaflet)
circleFun <- function(center = c(0,0),diameter = 1, npoints = 100){
r = diameter / 2
tt <- seq(0,2*pi,length.out = npoints)
xx <- center[1] + r * cos(tt)
yy <- center[2] + r * sin(tt)
Sr1 = Polygon(cbind(xx, yy))
Srs1 = Polygons(list(Sr1), "s1")
SpP = SpatialPolygons(list(Srs1), 1:1)
return(SpP)
}
Circle.Town <- circleFun(c(1,-1),2.3,npoints = 100)
df1 <- data.frame(long=c(0.6,1,1.4), lat=c(-2, -.8, -0.2), other=c('a', 'b', 'c'), VAM=c(10,8,6),
type=c('Public', 'Public', 'Private'), id=c(1:3)) %>%
mutate(X=paste0('<strong>id: </strong>',
id,
'<br><strong>type</strong>: ',
type,
'<br><strong>VAM</strong>: ',
VAM))
# Create a continuous palette function
pal <- colorNumeric(
palette = "RdYlBu",
domain = df1$VAM
)
leaflet(height = "400px") %>%
addTiles() %>%
addPolygons(data = Circle.Town, color = 'green', fillOpacity = .7) %>%
addCircleMarkers(data = df1, lat = ~lat, lng =~long,
radius = ~VAM, popup = ~as.character(X),
fillColor = ~pal(VAM),
stroke = FALSE, fillOpacity = 0.8,
clusterOptions = markerClusterOptions()) %>%
addLegend(position = "topright",
pal = pal, values = df1$VAM,
title = "VAM",
opacity = 1
) %>%
setView(lng = 1, lat = -1, zoom = 8)
现在,当我点击其中一个圆圈时,我会看到一个弹出窗口。当我悬停鼠标而不是单击时是否可以获取信息?理想情况下,我想要 this.
谢谢!
这是一个替代方案:
library(leaflet)
library(htmltools)
library(htmlwidgets)
yourmap <- leaflet(height = "400px") %>%
addTiles() %>%
addPolygons(data = Circle.Town, color = 'green', fillOpacity = .7) %>%
addCircleMarkers(data = df1, lat = ~lat, lng =~long,
radius = ~VAM, popup = ~as.character(X),
fillColor = ~pal(VAM),
stroke = FALSE, fillOpacity = 0.8,
clusterOptions = markerClusterOptions()) %>%
addLegend(position = "topright",
pal = pal, values = df1$VAM,
title = "VAM",
opacity = 1
) %>%
setView(lng = 1, lat = -1, zoom = 8)
setwd("~/Desktop/")
saveWidget(yourmap, file="yourmap.html")
在您的桌面上,您将有一个 html 和一个保存在您的地图下的文件夹。打开位于 /pathTo/yourmap_files/leaflet-binding-1.0.1.9002 中的 leaflet.js 文件。
在 leaflet.js 中,向下滚动到 var popup = df.get(i, 'popup');
并粘贴在下方:
marker.on('mouseover', function (e) {
this.openPopup();
});
marker.on('mouseout', function (e) {
this.closePopup();
});
保存并重新打开 yourmap.html 文件。将鼠标悬停在您的观点上!!
自一年前提出这个问题以来,这可能已添加到传单包中,但这可以通过 label
参数来完成。我正在使用传单 R 包版本 1.1.0。
如上读取数据:
library(sp)
library(leaflet)
library(dplyr)
circleFun <- function(center = c(0,0),diameter = 1, npoints = 100){
r = diameter / 2
tt <- seq(0,2*pi,length.out = npoints)
xx <- center[1] + r * cos(tt)
yy <- center[2] + r * sin(tt)
Sr1 = Polygon(cbind(xx, yy))
Srs1 = Polygons(list(Sr1), "s1")
SpP = SpatialPolygons(list(Srs1), 1:1)
return(SpP)
}
Circle.Town <- circleFun(c(1,-1),2.3,npoints = 100)
df1 <- data.frame(long=c(0.6,1,1.4), lat=c(-2, -.8, -0.2), other=c('a', 'b', 'c'), VAM=c(10,8,6),
type=c('Public', 'Public', 'Private'), id=c(1:3)) %>%
mutate(X=paste0('<strong>id: </strong>',
id,
'<br><strong>type</strong>: ',
type,
'<br><strong>VAM</strong>: ',
VAM))
# Create a continuous palette function
pal <- colorNumeric(
palette = "RdYlBu",
domain = df1$VAM
)
但是创建一个标签列表而不是矢量:
labs <- as.list(df1$X)
然后 lapply
HTML
函数在 label
参数中的那个列表上。注意使用 label
而不是 popup
.
library(htmltools)
leaflet(height = "400px") %>%
addTiles() %>%
addPolygons(data = Circle.Town, color = 'green', fillOpacity = .7) %>%
addCircleMarkers(data = df1, lat = ~lat, lng =~long,
radius = ~VAM, label = lapply(labs, HTML),
fillColor = ~pal(VAM),
stroke = FALSE, fillOpacity = 0.8,
clusterOptions = markerClusterOptions()) %>%
addLegend(position = "topright",
pal = pal, values = df1$VAM,
title = "VAM",
opacity = 1
) %>%
setView(lng = 1, lat = -1, zoom = 8)
这个方法在这个 SO 问题的答案中有描述:
传单文档中的标签中有关于 HTML 的更多信息:
