我想在ggplot2中创建一个散点图,其中带有"更改"等于"是"是红点,其余的是灰色的,而点是"重要的"等于"重要"有额外的绿色寄宿生,其余的有一个灰色寄宿生。 这是我的尝试:

structure(list(a = c(4.31316551, 5.7663368, 2.49063318, 5.83090286, 
3.11188057, 9.58084417, 4.08696886, 3.11188057, 6.43800344, 1.77771123, 
4.22594833), b = c(0.848363512, 0.045492721, 0.049883076, 0.136202457, 
0.572585532, 0.175069609, 0.000782666, 0.848363512, 0.254619199, 
0.378181529, 0.848363512), Significant = structure(c(1L, 2L, 
2L, 1L, 1L, 1L, 2L, 1L, 1L, 1L, 1L), .Label = c("no", "yes"), class = "factor"), 
    Change = structure(c(1L, 2L, 1L, 2L, 1L, 2L, 1L, 1L, 2L, 
    1L, 1L), .Label = c("no", "yes"), class = "factor")), .Names = c("a", 
"b", "Significant", "Change"), class = "data.frame", row.names = c(NA, 
-11L))

并输入数据:

<boolProp name="HTTPArgument.always_encode">false</boolProp>

两种不同的方法:

ggplot(data = df, mapping = aes(x=a,y=b)) + 
  geom_point(shape = 21, size=3, mapping = aes(fill=Change, color=Significant)) + 
  scale_fill_manual(values=c("grey", "red")) + 
  scale_color_manual(values=c("grey","green"))

ggplot(data = df, mapping = aes(x=a,y=b)) + 
  geom_point(data=df[df$Significant == "no",], color="grey", size=5) + 
  geom_point(data=df[df$Significant == "yes",], color="green", size=5) +
  geom_point(size=3, mapping = aes(color=Change)) + 
  scale_color_manual(values=c("grey","red"))
