更改 y 轴值的顺序
Change the order of the y-axis values
我正在使用 ggplot
R 包,我用下面的代码做了这个图:
p3 = data.frame(cbind(c(1:70),
c("G1" , "G2" , "G1" , "G1" , "G1" , "G2" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1",
"G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G2" , "G1" , "G2" , "G1" , "G1" ,
"G1" , "G1" , "G1" , "G2" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" ,
"G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" ,
"G1" , "G1" , "G1" , "G1" , "G2" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" , "G1" ,
"G1" , "G1" , "G1" , "G1" , "G2"),
c(rep("B",35),rep("C",15),rep("A",20))
))
colnames(p3)=c("Num","L" , "G")
library(ggthemes)
library(ggplot2)
pp <- ggplot(p3, aes(Num, G)) +
geom_tile(aes(fill = L), colour = "white")
pp + theme(legend.position="bottom", axis.text.x = element_text(angle=90, size=7,vjust=0.5)) + # scale_fill_grey() + theme_classic()
scale_fill_manual(values=c("#990000","#E69F00","#999999"))
我想根据柱数更改 y 轴值的顺序(= 变量 G)
预期剧情:
非常感谢您的帮助!
您可以设置数据框 G
列的排序方式,方法是将其设置为类型因子并设置级别。这一切都可以通过以下方式完成:
levels(p3$G) <- c("C", "A", "B")
根据 p3$G
变量的排序 table 更改 p3$G
的级别:
p3$G <- factor(p3$G, names(sort(table(p3$G))))
sort(table(p3$G))
# C A B
# 15 20 35
