我有一个结构如下的数据框
structure(list(Set = structure(c(1L, 1L, 1L, 2L, 2L, 2L), .Label = c("Set2",
"Set1"), class = "factor"), Subset = c("Feminine", "Masculine",
"Neutral", "Feminine", "Masculine", "Neutral"), Genderity = c(4.47,
-3.65, 1.54, 4.13, -4.03, -0.61)), row.names = c(NA, -6L), class = "data.frame")
我正在努力在ggplot 2中复制它(下面是我的代码,即使它提供的输出与预期的相似)y轴上的空格也很远,因为我在x和y参数中都使用了Genderity。如果我将y参数留空
ggplot(aes(x=Genderity, y=Genderity), data=df_2, position="stack", stat="identity")+
geom_bar(stat="identity",aes(fill=Subset),position="dodge")+
coord_flip()+
geom_hline(yintercept = 0, color =c("black")) +
scale_y_continuous(breaks=seq(-5,5,1), limits=c(-5,5))+
facet_wrap(facets = .~Set, ncol = 2, nrow=1)
我知道我的输出确实接近我想要的输出,但它不是正确的输出方式。请帮助通过ggplot 2做到这一点

这似乎是将Subset
字符串转换为一个因子的好地方,这将使您可以根据需要对其进行排序。请注意,在定义映射时,我使用fct_rev
将女性栏置于顶部,与图例对齐,该图例按顺序显示了各个因素。
df_2_mod <- df_2 %>%
mutate(Subset = fct_relevel(Subset, "Feminine", "Neutral", "Masculine"))
ggplot(df_2_mod,
aes(x=Subset %>% fct_rev(), y=Genderity, fill = Subset))+
geom_col()+ # geom_col uses values by default, vs. counts for geom_bar
coord_flip()+
geom_hline(yintercept = 0, color =c("black")) +
facet_wrap(facets = .~Set, nrow=1) +
labs(x="")

我们可以尝试解决方法:
# add a fake column
df_2$fake <-rownames(df_2)
library(ggplot2)
# we add as x the fake
ggplot(aes(x=fake, y=Genderity), data=df_2, position="stack")+
geom_bar(stat="identity",aes(fill=Subset),position="dodge")+
coord_flip()+
geom_hline(yintercept = 0, color =c("black")) +
scale_y_continuous(breaks=seq(-5,5,1), limits=c(-5,5))+
# to avoid riffle, we use the scales="free" option
facet_wrap(facets = .~Set, ncol = 2, nrow=1,scales="free")+
# last, we make blank the y axis
theme(axis.title.y=element_blank(),
axis.text.y=element_blank(),
axis.ticks.y=element_blank())
而且,如果您想在模型中订购该订单,并且还希望x轴空白,可以尝试以下操作:
# the reorder option:
ggplot(aes(x=reorder(fake,Genderity), y=Genderity), data=df_2, position="stack")+
geom_bar(stat="identity",aes(fill=Subset),position="dodge")+
coord_flip()+
geom_hline(yintercept = 0, color =c("black")) +
scale_y_continuous(breaks=seq(-5,5,1), limits=c(-5,5))+
facet_wrap(facets = .~Set, ncol = 2, nrow=1,scales="free")+
theme(axis.title.y=element_blank(),
axis.text.y=element_blank(),
axis.ticks.y=element_blank(),
# x-axis blank:
axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
并且:
+ ggtitle("Conveyed gender")
会给你标题。
编辑:
要添加标签,您必须:
p <- ggplot(aes(x=reorder(fake,Genderity), y=Genderity), data=df_2, position="stack")+
geom_bar(stat="identity",aes(fill=Subset),position="dodge")+
coord_flip()+
geom_hline(yintercept = 0, color =c("black")) +
scale_y_continuous(breaks=seq(-5,5,1), limits=c(-5,5))+
facet_wrap(facets = .~Set, ncol = 2, nrow=1,scales="free")+
theme(axis.title.y=element_blank(),
axis.text.y=element_blank(),
axis.ticks.y=element_blank(),
# x-axis blank:
axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
p <- p + ggtitle("Conveyed gender") + geom_text(aes(label=Genderity), hjust=1)
p
或者您也可以使用:
+ geom_text(aes(label = Genderity), position = position_dodge(0.9))
