Question

我试图将我的数据表示为方框图，我的数据框目前看起来如下：

  V1    V2     V3         V4       V5
1  1 12.18 FEMALE A_ambiguus     Host
2  2 11.81 FEMALE A_ambiguus     Host
3  3 10.70   MALE A_ambiguus     Host
4  4 11.07   MALE A_ambiguus     Host
5  5  7.95 FEMALE  A_ameliae Parasite
6  6  7.42 FEMALE  A_ameliae Parasite

我运行以下脚本并生成一个图形，其中物种（V4）为x轴，总长度（V2）为y轴，按V2排序，并用V5着色。

box <- ggplot(TL_sub, aes(x = V4, y = V2, group = V4)) +
  scale_y_continuous(name = "TL (mm)") +
  theme(axis.text.x=element_text(angle = 45, hjust = 1)) +
  geom_boxplot(aes(fill=Condition)) +
  aes(x=reorder(V4,V2),y=V2,label=TL)

box

Sorted boxplot of all data

问题在于，当我运行

时

box + facet_grid(. ~ V5)

目标是创建两个按性别划分的图（V3），但它不起作用。我收到以下错误：

Error in combine_vars(data, params$plot_env, cols, drop = params$drop) : 
  At least one layer must contain all variables used for facetting

如果需要，我可以提供完整的数据集。

任何帮助都会很棒！谢谢，史蒂文M。

Answer 1

使用完整的数据集，这对我来说很好。

TL_subset %>% 
  ggplot(aes(reorder(Species, TL), TL)) + 
    geom_boxplot(aes(fill = Condition)) + 
    labs(x = "Species", y = "TL (mm)") + 
    theme(axis.text.x = element_text(angle = 45, hjust = 1)) + 
    facet_grid(. ~ Sex)

Answer 2

以下是您的示例数据中的另一个示例

dataset<-data.frame(V2=c(12.18,11.81,10.70,11.07,7.95,7.42),
                    V3=c("FEMALE","FEMALE","Male","Male","FEMALE","FEMALE"),
                    V4=c("A_ambiguus","A_ambiguus","A_ambiguus","A_ambiguus","A_ameliae","A_ameliae"),
                    V5=c("Host","Host","Host",'Host',"Parasite","Parasite"))                 


library(ggplot2)

ggplot(data=dataset,aes(x=V4,y=V2)) + geom_boxplot(aes(fill=V5))+facet_grid(.~V3) +xlab("Species") +
  ylab("TL (mm)") + scale_fill_discrete(name="Condition")

我遵循了示例，我无法让facet_grid来分割我的数据
