我试图在这个地图数据框中添加与特定国家相对应的特定变量

library(maps)

countries <- c("Australia", "South Africa", "India", "Mexico", "USA", "Russia")
genes <- c("gene1","gene2","gene3","gene4","gene5","gene6")

bounds <- map("world", countries, fill = TRUE, plot = FALSE)

bounds$genes <- genes

库（地图）

国家你可以这样做


bounds$genes <- genes[match(gsub("\\:.*", "", bounds$names), countries)]



bounds$genes是的，这确实有效，非常感谢，这是一个简单的解决方案！
