ggalluvial 为每个节点分配不同的颜色

Question

我一直在关注这个 post，但我不知道如何用我的数据管理它。

我的剧情是这样的：

我希望“字符串”的颜色与第二列相同，即对于 ESR1，我希望使用橙色字符串，对于 PIK3CA，我希望使用绿色。关于如何使用 scale_fill_manual 或任何其他参数进行管理的任何想法？

谢谢！

我的代码：

colorfill <- c("white", "white", "darkgreen", "orange", "white", "white", "white", "white", "white", "white", "white", "white", "white", "white", "white", "white", "white")
ggplot(data = Allu,
       aes(axis1 = Gene_mut, axis2 = Metastasis_Location, y = Freq)) +
  geom_alluvium(aes(fill = Gene_mut),
                curve_type = "quintic") +
  geom_stratum(width = 1/4, fill = colorfill) +
  geom_text(stat = "stratum", size = 3,
            aes(label = after_stat(stratum))) +
  scale_x_discrete(limits = c("Metastasis_Location", "Gene_mut"),
                   expand = c(0.05, .05)) +
  theme_void()

我的数据：

Answer 1

你的想法是对的scale_fill_manual()。我认为这是将 colorfill 之类的向量传递给 aes() 之外的美学的更可编程的替代方法。下图使用您的数据和颜色向量来控制 fill 美学在整个图中的编码方式，并注意 fill 在两个图层（冲积层）中传递了相同的变量 Gene_mut和阶层）：

ggplot(data = Allu,
       aes(axis1 = Gene_mut, axis2 = Metastasis_Location, y = Freq)) +
  geom_alluvium(aes(fill = Gene_mut),
                curve_type = "quintic") +
  geom_stratum(aes(fill = Gene_mut), width = 1/4) +
  scale_fill_manual(values = colorfill) +
  geom_text(stat = "stratum", size = 3,
            aes(label = after_stat(stratum))) +
  scale_x_discrete(limits = c("Metastasis_Location", "Gene_mut"),
                   expand = c(0.05, .05)) +
  theme_void()

由于 Metastasis_Location 采用与 Gene_mut 不同的值，fill 将这些层视为具有缺失值，默认情况下为灰色。您可以通过将颜色字符串传递给 scale_fill_manual().
