R - 在Leaflet地圖上的plotMapDomFlows（“flow”包）

Question

R中有一個名為“flow”的軟件包（詳見此處） ，它允許您繪制流交互圖（通過函數plotMapDomFlows（）從平方流的矩陣中繪制 。這是一個示例，包含數據，輸出的樣子：

# Import data
data(nav)
myflows <- prepflows(mat = nav, i = "i", j = "j", fij = "fij")

# Remove the matrix diagonal
diag(myflows) <- 0

# Select flows that represent at least 20% of the sum of outgoing flows for 
# each urban area.
flowSel1 <- firstflows(mat = myflows/rowSums(myflows)*100, method = "xfirst", 
                       k = 20)


# Select the dominant flows (incoming flows criterion)
flowSel2 <- domflows(mat = myflows, w = colSums(myflows), k = 1)

# Combine selections
flowSel <- myflows * flowSel1 * flowSel2

# Node weights
inflows <- data.frame(id = colnames(myflows), w = colSums(myflows))

# Plot dominant flows map
opar <- par(mar = c(0,0,2,0))
sp::plot(GE, col = "#cceae7", border = NA)
plotMapDomFlows(mat = flowSel, spdf = UA, spdfid = "ID", w = inflows, wid = "id",
                wvar = "w", wcex = 0.05, add = TRUE)

我想在使用R的傳單地圖上有這些線和多邊形。

有任何想法嗎？

目前這是不可能的。 我們計划盡快更新套餐。 此功能（行和點導出）可能是更新引入的新功能之一。
