我想在其中添加一列，可以为每个途径术语分配颜色。

在我的数据框中，我拥有dim(d2) [1] 190 7和存在的级别

分配颜色的目的是我想将此数据框用于waffle图表

我试过这个链接不能让它工作。任何建议将不胜感激

我在链接到您的数据时遇到问题。你介意检查它是否正常工作吗？

您可以使用这些函数之一为每个因子级别生成十六进制代码

rainbow()
heat.colors()
terrain.colors()
topo.colors()
cm.colors()

这是我想到的一种方法

lookup <- data.frame(
  color = rainbow(n = length(unique(d2$Pathway))),
  Pathway = unique(d2$Pathway))
 
# merge lookup table with original dataframe                   
d3 <- merge(d2, lookup, by = "Pathway")
