当我在 R 中使用传单包(不是leafletR)创建 map 时，它不会转换我的丹麦语字符。他们似乎都被打乱了。我找不到解决方案。该问题会影响图例和弹出窗口。
代码如下所示:
colorscale = colorNumeric("YlOrRd", domain = NULL)
data_popup <- paste0("Med en gennemsnitsalder på <strong>", round(kommuner$`NUVÆRENDE ALDER`,2), "</strong> år ligner ",
"<strong>", kommuner$name, "</strong> mest Danmark i år ",
"<strong>", kommuner$ÅRSTAL,
ifelse(kommuner$ÅRSTAL > 2015, "</strong>, hvor gennemsnitsalderen vil være ", "</strong>, hvor gennemsnitsalderen var "),
"<strong>", round(kommuner$`ÅRSTAL ALDER`,2), "</strong> år")
kort <- leaflet(kommuner) %>% addProviderTiles("CartoDB.Positron") %>%
addPolygons(fillColor = ~colorscale(ÅRSTAL),
fillOpacity = 0.8,
color = "#BDBDC3",
weight = 1,
popup = data_popup) %>%
addLegend("bottomright", pal = colorscale, values = ~ÅRSTAL,
title = "Årstal",
labFormat = labelFormat(prefix = "År ", big.mark = ""),
opacity = 1) %>%
setView(10.533880, 56.114586, zoom=8)
kort
我该如何解决这个问题？
更新:可重现的例子
library(sp)
Sr1 = Polygon(cbind(c(2, 4, 4, 1, 2), c(2, 3, 5, 4, 2)))
Sr2 = Polygon(cbind(c(5, 4, 2, 5), c(2, 3, 2, 2)))
Sr3 = Polygon(cbind(c(4, 4, 5, 10, 4), c(5, 3, 2, 5, 5)))
Sr4 = Polygon(cbind(c(5, 6, 6, 5, 5), c(4, 4, 3, 3, 4)), hole = TRUE)
Srs1 = Polygons(list(Sr1), "s1")
Srs2 = Polygons(list(Sr2), "s2")
Srs3 = Polygons(list(Sr4, Sr3), "s3/4")
SpP = SpatialPolygons(list(Srs1, Srs2, Srs3), 1:3)
df <- data.frame(a = c("A", "B", "C"), b = c("Æ", "Ø", "Å"))
data_popup <- paste0(df$a, " is no problem.",
"<br>",df$b, " is a problem.")
library(leaflet)
leaflet(height = "300px") %>% addPolygons(data = SpP, popup = data_popup)
单击空间多边形时，我无法读取“Æ、Ø 和 Å”

最佳答案
我认为，整体解决方案是使用 UTF-8 字符编码(参见: https://en.wikipedia.org/wiki/UTF-8 )作为您计算机系统的基础。简而言之，放弃使用“Danish_Denmark.[ISO]1252” - 或者就此而言“Slovenian_Slovenia.[ISO]1250”。这么说是因为我认为大多数语言特定的字母应该已经在 UTF-8 中可用。
作为传单图尝试的临时解决方案，在 RStudio 中:工具 > 项目选项 ... > 代码编辑 > 文本编码 > 更改 ....(到 UTF-8)。
希望这有效，
