使用这个假人 data.frame

ts <- data.frame(x=1:3, y=c("blue", "white", "white"), z=c("one", "one", "two"))

我尝试用顶部的"蓝色"类别绘图.

ggplot(ts, aes(z, x, fill=factor(y, levels=c("blue","white" )))) + geom_bar(stat = "identity")

给我"白色"在上面.和

ggplot(ts, aes(z, x, fill=factor(y, levels=c("white", "blue")))) + geom_bar(stat = "identity")

颠倒颜色,但仍然让我在上面"白色".我怎样才能获得"蓝色"？

我的同事和我正在尝试根据y值排序堆积条形图,而不是按x字母顺序排列.

样本数据是:

samp.data <- structure(list(fullname = c("LJ", "PR", 
"JB", "AA", "NS", 
"MJ", "FT", "DA", "DR", 
"AB", "BA", "RJ", "BA2", 
"AR", "GG", "RA", "DK", 
"DA2", "BJ2", "BK", "HN", 
"WA2", "AE2", "JJ2"), I = c(2L, 
1L, 3L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 2L, 3L, 3L, 3L, 
3L, 3L, 3L, 3L, 3L, 3L, 3L), S = c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 
2L, 2L, 2L, 2L, 3L, 2L, 3L, 2L, 2L, 2L, 3L, 2L, 3L, 2L, 3L, …

我注意到在使用绘图创建的直方图中填充条形的默认值是反向字母顺序,而图例按字母顺序排序.我有什么方法可以按字母顺序排序吗？问题在下面的示例图中很明显.奖金问题:我如何将从左到右的条形顺序从字母顺序更改为减少计数总数？谢谢

df <- data.frame(
  Site=c("A05","R17","R01","A05","R17","R01"),
  Group=c("Fungia","Fungia","Acro","Acro","Porites","Porites"),
  Count=c(6,8,6,7,2,9),
  Total=c(13,10,15,13,10,15)
)

  Site   Group Count Total
1  A05  Fungia     6    13
2  R17  Fungia     8    10
3  R01    Acro     6    15
4  A05    Acro     7    13
5  R17 Porites     2    10
6  R01 Porites     9    15

qplot(df$Site,data=df,weight=df$Count,geom="histogram", fill=df$Group, ylim = c(0,16)) + 
  xlab("Sites") + 
  ylab("Counts") + 
  scale_fill_hue(h=c(0,360), l=70, c=70,name = "Emergent Groups")

我试图将计数从高到低和填充颜色排序,以便它们匹配图例的字母顺序.我一直试图用初始帖子的提示调整它几个小时但没有成功.任何有关这方面的帮助将非常感谢!!!
