另一个有趣的ggplot2挑战!我正在尝试创建一个ggsubplot调用,在世界地图上提供饼图.艰难的事情似乎是ggplot2中的饼图是带有极坐标的堆积条形图,并且coord_polar的添加不仅影响子图geom而且影响整个地图本身.有没有人知道如何仅将某个坐标方案应用于子图调用的一部分？这是我到目前为止:

11L, 12L, 13L, 15L, 16L, 2L, 14L, 2L, 4L, 5L, 6L, 7L, 9L, 10L
), .Label = c("", "ANT/SO", "ARC", "EPR/GAL", "GOM/CAR", "IND",
"MAR", "MED", "N-ATL", "NE-ATL", "NE-PAC", "NW-ATL", "NW-PAC",
