  以下是我将样本数据转换为数据帧的方法（尽管下次您真的应该使用 dput 来共享数据）：

  df = read.table(text = "
              sat -0.038685744            
              sun -0.004397419            
              mon -0.072163337            
              tue 0.123328564         
              wed 0.021875962         
              thu 0.005030862         
              fri 0.002869955 ")
  colnames(df) = c("day", "thing")
  

  以下是我将数据框转换为条形图的方法：

  library(ggplot2)
  ggplot(df, aes(day, thing)) + geom_bar(stat = "identity")

  下次以可重复的方式呈现数据，以便其他人不再重新键入它 .

  # your data 
  df <- tribble(
    ~week_day, ~value,
    "sat", -0.038685744,            
    "sun", -0.004397419,           
    "mon", -0.072163337,            
    "tue", 0.123328564,         
    "wed", 0.021875962,         
    "thu", 0.005030862,         
    "fri", 0.002869955 
  )
  df
  
  ordered <- c("sun", "mon", "tue", "wed", "thu", "fri", "sat")
  df$week_day <- factor(df$week_day, levels = ordered)
  
  ggplot(df, aes(x = week_day, y = value, group = 1)) +
    geom_point() +
    geom_line()
  

  [代码根据Gregor的建议调整]
