r - 如何在 R 的条形图中对 X 轴进行排序？

Question

我的分箱数据如下所示:

我如何绘制这些数据，以便 bin 从左侧的最负值到右侧的最正值排序？目前我的图表看起来是like this .请注意，它根本没有排序。特别是第二个栏 (value = 76) 位于第一个栏的右侧:

 (8.048,18.05] (-21.95,-11.95]
            81              76

这是我用来绘图的命令:

barplot(x,ylab="Number of Unique Tags", xlab="Expected - Observed")

我真的很想帮助回答您的问题，但我必须告诉您，我无法判断您的数据的正反面。我看到很多左括号但没有右括号。数据看起来按每行底部的值降序排列。我不知道如何使用“(8.048,18.05]”这样的值

我是否遗漏了一些明显的东西？您能否举一个更简单的示例，其中您的数据结构不是一个因素？

我通常希望数据框或矩阵有两列，一列用于 X，一列用于 Y。

看看这个排序示例是否有帮助(我在这里是在黑暗中拍摄)

tN <- table(Ni <- rpois(100, lambda=5))
r <- barplot(tN)

#stop here and examine the plot
#the next bit converts the matrix to a data frame,
#  sorts it, and plots it again

df<-data.frame(tN)
df2<-df[order(df$Freq),]
barplot(df2$Freq)
