R：ggplot2 stat_bindot 圆/圆点的替代方案 - 产生错误

Question

我目前正在使用以下代码在热图上显示矩形图：

stat_bin2d(bins = 19, aes(fill = after_stat(density))) +

出现以下错误：could not find function "stat_bindot"

我用谷歌搜索了这个问题，发现可能是该功能在最新版本中被删除了。

我还能如何将点绘制为圆而不是矩形？

示例代码：

数据集是要绘制的 X 和 Y 坐标列表（在单独的列中）。

library(ggplot2)

ggplot(data = my.project_data, aes(x = CoordX,y = CoordY)) + 
  sstat_bin2d(bins = 19, aes(fill = after_stat(density))) +
  scale_fill_gradient(name = "Percent", 
                  low = "#DDDDDD",
                  high = "#000000",
labels = scales::percent)

Answer 1

如果你想把类似方块的显示改为圆形，你可以把geom参数改为stat_bin2d()。下面是标准数据集的示例：

library(ggplot2)

ggplot(data = faithful, aes(x = eruptions, y = waiting)) + 
  stat_bin2d(bins = 19, aes(colour = after_stat(density),
                            fill = NULL),
             geom = "point", size = 5) +
  scale_colour_gradient(name = "Percent", 
                        low = "#DDDDDD",
                        high = "#000000",
                        labels = scales::percent)
