ggalluvial（r 包）示例给出错误

Question

我错过了什么吗？ ggalluvial 包中的示例给出了这个错误：

> library(ggalluvial)
> ggplot(as.data.frame(Titanic),
+        aes(weight = Freq,
+            axis1 = Class, axis2 = Sex, axis3 = Age,
+            fill = Survived)) +
+   geom_alluvium() +
+   scale_x_continuous(breaks = 1:3, labels = c("Class", "Sex", "Age"))
Error: Invalid column specification

更新 2：根据 DanHall 的要求：

Answer 1

见下文，此代码可在另一台机器上运行。当对其他人有用的东西对你不起作用时，运行 update.packages() 并按照说明更新你可能已安装的任何过时的软件包会很有用。这就是这里的解决方案。

它在我的机器上按原样运行：

ggplot(as.data.frame(Titanic),
      aes(weight = Freq, 
          axis1 = Class, axis2 = Sex, axis3 = Age,
          fill = Survived)) +
  geom_alluvium() +
    scale_x_continuous(breaks = 1:3, labels = c("Class", "Sex", "Age"))

调用example(geom_alluvium, package = "ggalluvial")时也有效。

这是另一个用法示例（来自小插图）。

ggplot(as.data.frame(Titanic),
       aes(weight = Freq,
           axis1 = Survived, axis2 = Sex, axis3 = Class)) +
  geom_alluvium(aes(fill = Class),
                width = 0, knot.pos = 0, reverse = FALSE) +
  guides(fill = FALSE) +
  geom_stratum(width = 1/8, reverse = FALSE) +
  geom_text(stat = "stratum", label.strata = TRUE, reverse = FALSE) +
  scale_x_continuous(breaks = 1:3, labels = c("Survived", "Sex", "Class")) +
  coord_flip() +
  ggtitle("Titanic survival by class and sex")
