这个问题在这里已有答案:

问候,

我在使用facet_wrap在ggplot2中正确命名标签时遇到了一些困难 . 我的图表代码是:

library(ggplot2)

mlm.plots <- ggplot(positions.df, aes(x, y)) +
geom_point(size=0.75, shape=1, colour="darkred", fill="pink")+
geom_abline(data = multilevel.df, aes(intercept=V2, slope=V3, 
group=party), color="red", size=.1)+
facet_wrap(~party, ncol=2) +
xlab("")+
ylab("")

这产生以下结果:

Multilevel model plot of Finnish political parties

我真正想要的不是标签(“1”,“2”......)而是在每种情况下都有政党的名字 . 我觉得应该有一个优雅的解决方案使用labeller(),但我无法想出一个 .

我认为部分问题在于我将聚会设置为如下因素:

party <- as.factor(rep(c("National Coalition Party", "Centre Party", 
"Social Democratic Party", "Left Alliance", "Christian Democrats", 
"True Finns", "Swedish People's Party",   "Greens"), J))

我也知道,如果派对是一个字符,情节就会非常糟糕 .

制作图表的数据如下:

structure(list(party = c(5, 1, 6, 4, 2, 8, 7, 3, 5, 1, 6, 4, 
2, 8, 7, 3, 5, 1, 6, 4, 2, 8, 7, 3, 5, 1, 6, 4, 2, 8, 7, 3, 5, 
1, 6, 4, 2, 8, 7, 3, 5, 1, 6, 4, 2, 8, 7, 3, 5, 1, 6, 4, 2, 8, 
7, 3, 5, 1, 6, 4, 2, 8, 7, 3), x = c(-16.667, -36.735, 43.243,

    party 列转换为factor时,请使用 labels 参数指定标签 .

    positions.df$party <- factor(positions.df$party,
                                 labels = c("National Coalition Party", "Centre Party", 
                                            "Social Democratic Party", "Left Alliance", "Christian Democrats", 
                                            "True Finns", "Swedish People's Party",   "Greens"))
    
    multilevel.df$party <- factor(multilevel.df$party,
                                  labels = c("National Coalition Party", "Centre Party", 
                                             "Social Democratic Party", "Left Alliance", "Christian Democrats", 
                                             "True Finns", "Swedish People's Party",   "Greens"))
    

    之后,您可以使用原始代码绘制数据 .

    mlm.plots <- ggplot(positions.df, aes(x, y)) +
      geom_point(size=0.75, shape=1, colour="darkred", fill="pink")+
      geom_abline(data = multilevel.df, aes(intercept=V2, slope=V3, 
                                            group=party), color="red", size=.1)+
      facet_wrap(~party, ncol=2) +
      xlab("")+
      ylab("")
    
    mlm.plots
