我正在使用geom_scatterpie映射数据。但是，要么我的地图歪斜，要么我的饼图歪斜。使用 coord_map/coord_fixed 时，我不能单独使用这些功能。如何确保我的地图和饼图看起来“正常”？

这是我运行的代码：

ggplot()+ geom_polygon(data = NLD_fixed, aes(x = long, y = lat, group = group), 
                       fill= 'gray',colour = "white")+ 
                       geom_scatterpie(data=DF,aes(x=V9, y=V8, r=total/150),
                       cols = c("A","B", "C"),
                       alpha=.3)

提前致谢！

编辑：我的代码的目标是绘制不同地区的饼图，这样我就可以看到一些技术的生产地点、数量和哪些（因此是饼图）。如您所见，我的饼图是倾斜的。如果我使用 coord_fixed，我的底图就会倾斜。

地图

df<- structure(list(V8 = c(50.85, 51.4478875, 51.45, 51.966667, 52), 
                    V9 = c(5.683333, 5.4859493, 5.466667, 5.666667, 4.366667), 
                    Bio = c(1, 0, 1, 1, 0), Comp = c(0, 0, 2, 0, 16), 
                    EnConv = c(0, 2, 1, 0, 5)), row.names = c(NA, -5L), 
                    class = c("grouped_df", "tbl_df", "tbl", "data.frame"), 
                    groups = structure(list(V8 = c(50.85, 51.4478875, 51.45, 51.966667, 52), 
                    .rows = list(1L, 2L, 3L, 4L, 5L)), row.names = c(NA, -5L), 
                    class = c("tbl_df", "tbl", "data.frame"), .drop = TRUE))

我已经尝试了类似问题的方法（使用 ggplot 添加到投影地图时 R 饼图失真）第 1 步：

  tidyr::gather(type, value, -V8, -V9, -total,-V10, -City) %>%
  tidyr::nest(type, value)

使用数据集：

structure(list(V8 = c(50.85, 51, 51.44789, 51.45, 51.85, 51.966667, 
52, 52.091, 52.15, 52.216667, 52.25, 52.35, 52.766667, 53.2, 
53.216667), V9 = c(5.683333, 5.766667, 5.866667, 5.466667, 5.75,

    2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 13L, 14L, 
    15L)), row.names = c(NA, -15L), class = c("tbl_df", "tbl", 
"data.frame"), .drop = FALSE))

（警告信息：'...' 的所有元素都必须命名。你想要data = c(type, value)吗？）

但是当我尝试第 2 步时（添加到我的数据集中）

mutate(pie.grob = purrr::map(data,
                               function(d) ggplotGrob(ggplot(d, 
                                                             aes(x = 1, y = value, fill = type)) +
                                                        geom_col(color = "black",
                                                                 show.legend = FALSE) +
                                                        coord_polar(theta = "y") +
                                                        theme_void())))

我收到错误：错误：.x 必须是向量，而不是我尝试过使用第一个代码和第二个代码的函数，但似乎无法正确处理。提前致谢！
