GGPLOT多面条形图：每个填充类别有多个“闪避”条形图？

我策划这个数据集 'DS'GGPLOT多面条形图：每个填充类别有多个“闪避”条形图？

ds <- structure(list(FN = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 
          3L, 4L, 4L, 4L, 1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L, 4L, 4L, 4L, 
          1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L, 4L, 4L, 4L, 1L, 1L, 1L, 2L, 
          2L, 2L, 3L, 3L, 3L, 4L, 4L, 4L), .Label = c("FN=1", "FN=2", "FN=3", 
          "FN=4"), class = "factor"), fraction = structure(c(1L, 1L, 1L, 
          1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 
          1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 
          2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("serum", 
          "plasma"), class = "factor"), demographics = structure(c(1L, 
          1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 
          2L, 2L, 2L, 2L, 2L, 2L, 2L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 
          1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("not adjusted", 
          "adjusted"), class = "factor"), freq = c(132, 47, 14, 30, 29, 
        19, 25, 14, 9, 5, 4, 4, 24, 21, 15, 6, 6, 5, 4, 4, 2, 2, 2, 2, 
        35, 28, 25, 68, 24, 11, 33, 15, 10, 12, 11, 8, 24, 16, 15, 13, 
        10, 6, 7, 6, 5, 4, 3, 3)), .Names = c("FN", "fraction", "demographics", 
      "freq"), class = "data.frame", row.names = c(NA, -48L))

使用此ggplot码

ggplot(ds, aes(x=fraction, y=freq, fill=factor(demographics, c("adjusted", "not adjusted")))) + 
    geom_bar(position=position_dodge(width=0.9), stat="identity", color="black") + 
    facet_grid(FN~., switch="y") + 
    scale_fill_manual("", values=c("not adjusted"="#e41a1c", "adjusted"="#377eb8"), guide=guide_legend(reverse = TRUE)) + 
    theme_bw() + 
    theme(legend.title=element_blank(), legend.position="bottom") + 
    theme(axis.title.x=element_text(face="bold")) + 
    theme(axis.title.y=element_blank()) + 
    theme(axis.ticks=element_blank()) + 
    theme(panel.background=element_blank()) + 
    theme(panel.grid=element_blank()) + 
    theme(strip.text.y = element_text(angle=180)) + coord_flip()

返回这个结果

正如你所看到的，每个x变量“分数”（血清/血浆）和填充类别“人口统计”（未调整/调整）是三个条形图。不过，我希望这些三个酒吧每个填充类别人口统计图并排绘制。这甚至有可能吗？

你的帮助是极大的赞赏！

添加一个单独的分组变量

library("tidyverse") 
ds %>% mutate(row = row_number()) %>% 
ggplot(aes(x=fraction, y=freq, fill=factor(demographics, c("adjusted", "not adjusted")), group = row)) + 
    geom_bar(position=position_dodge(width=0.9), stat="identity", color="black") + 
    facet_grid(FN~., switch="y") + 
    scale_fill_manual("", values=c("not adjusted"="#e41a1c", "adjusted"="#377eb8"), guide=guide_legend(reverse = TRUE)) + 
    theme_bw() + 
    theme(legend.title=element_blank(), legend.position="bottom") + 
    theme(axis.title.x=element_text(face="bold")) + 
    theme(axis.title.y=element_blank()) + 
    theme(axis.ticks=element_blank()) + 
    theme(panel.background=element_blank()) + 
    theme(panel.grid=element_blank()) + 
    theme(strip.text.y = element_text(angle=180)) + 
    coord_flip()

感谢您的快速和准确的答案。还有一个问题，你知道我怎么能改变酒吧的顺序，以便'红色'（未调整）在'蓝色'之前或之上绘制？ –

把你想要的第一个放在'scale_fill_manual'中，所以'scale_fill_manual（“”，values = c（“adjusted”=“＃377eb8”，“not adjusted”=“＃e41a1c”）...' –

听起来似乎是合理的，然而，这对我不起作用，也许是由于翻转了这个阴谋？ –

眼下列跨demographics躲开了，但如果你添加更多的aestetic（内aes()功能）group=freq ggplot将分别躲闪每个酒吧。因此，你的代码应该阅读：

ggplot(ds, aes(x=fraction, y=freq, group=freq, fill=factor(demographics, c("adjusted", "not adjusted")))) + 
    geom_bar(position=position_dodge(width=0.9), stat="identity", color="black") + 
    facet_grid(FN~., switch="y") + 
    scale_fill_manual("", values=c("not adjusted"="#e41a1c", "adjusted"="#377eb8"), guide=guide_legend(reverse = TRUE)) + 
    theme_bw() + 
    theme(legend.title=element_blank(), legend.position="bottom") + 
    theme(axis.title.x=element_text(face="bold")) + 
    theme(axis.title.y=element_blank()) + 
    theme(axis.ticks=element_blank()) + 
    theme(panel.background=element_blank()) + 
    theme(panel.grid=element_blank()) + 
    theme(strip.text.y = element_text(angle=180)) + coord_flip()

这将是这样的：

这适用于当前数据集，但如果来自同一组的两行具有相同的freq值 –
