我正在尝试用R而不是数字创建R的欧洲海图地图。
可以说我下面有数据集,我希望地图显示每个类别的颜色。类别为:“红色”,“蓝色”,“绿色”。
library(highcharter)
mapData <- data_frame(country = c("PT", "FR", "IT", "DE"),
value = c("Red","Blue","Green","Red"))
然后我需要地图来显示类别:
hcmap(map = 'custom/europe', data = mapData,
joinBy = c("iso-a2","country"), value = "value")
问题是,结果使我的data frame
中的每个国家/地区都变得黑了。
答案 0 :(得分:2)
以下是可能解决方案的建议:
mapData <- tibble(country = c("PT", "FR", "IT", "DE"),
value = c(1, 2, 3, 1))
hcmap(map = 'custom/europe', data = as.data.frame(mapData),
joinBy = c("iso-a2","country"), value = "value") %>%
hc_colorAxis(dataClassColor="category",
dataClasses = list(list(from=1, to=1, color="red", name="PT-DE"),
list(from=2, to=2, color="blue", name="FR"),
list(from=3, to=3, color="green", name="IT")))
