Question

我想给每个方面一个alpha代码，从A到H，因为有八个方面，并在每个方面的左上角绘制每个代码：

ggthemr('dust', layout = 'scientific',
        spacing = 1, type = 'inner', line_weight = 0.6,
        )

ptitles <- c('A' = "Total mass (g)", 'B' = "Root mass (g)", 'C' = "Stem mass (g)",
    'D' = "Leaf mass (g)", 'E' = "Number of nodes",
    'F' = "Number of leaves", 'G' = "Total stem length (cm)", 'H' = "RDI")

ggplot(gtr, aes(sediment, value)) +
    geom_boxplot(aes(fill = nitrogen)) +
    geom_text(aes(label = trait, group = trait)) +
    facet_wrap(~trait, scales = "free_y", ncol = 2,
        labeller = as_labeller(ptitles),
        strip.position = "left"
        ) +

theme(legend.position = "bottom",
    legend.title = element_text(size = 12),
    legend.key.size = unit(2, "lines"),
    legend.text = element_text(size = 12),
    strip.text.x = element_text(size = 12, margin = margin(0, 0, 0, 10)),
    strip.text.y = element_text(size = 14),
    strip.placement = "outside",
    axis.title.y = element_text(size = 14),
    axis.title.x = element_text(size = 14),
    axis.text.x = element_text(size = 14),
    panel.spacing.x = unit(0.5, "lines"),
    panel.spacing.y = unit(0.3, "lines"),
    aspect.ratio = 2 / 3
    ) +

xlab("Effects of sediment type and nitrogen deposition") +
ylab(NULL)

我尝试使用geom_text（）：

geom_text(aes(label = trait, group = trait))

（此处变量trait存储从A到H的因子以区分每个方面）但它没有像我预期的那样工作：

这种事情有简单的方法吗？

更新

根据 baptiste 的回答，我将上面的geom_text（）代码更改为以下内容：

    geom_text(aes(x = -Inf, y = Inf, label = trait, group = trait),
        size = 5,
        hjust = -0.5,
        vjust = 1.4,
        inherit.aes = FALSE)

inherit.aes = FALSE这里好像什么也没做，这个参数怎么工作？。

现在我的情节很好看：

Answer 1

import java.util.Scanner; 
import java.util.Arrays;

public class Unit03Prog2 { 
   public static void main(String[] args) {
       //Array 
       int Numbers[] = new int[10];
       Scanner Numb = new Scanner(System.in);
       int j = 0;
       int inputNumber;
       boolean isDuplicate;

       for(int i=0; i < Numbers.length; i++){ 
           isDuplicate = false;
           System.out.print("Enter an integer: "); 

           //Stores it, and moves to the next line 
           inputNumber = Numb.nextInt(); 

          //Removes duplicates 
         //Code to remove duplicates goes here VVVV //Ends it if i = 10 
         for (int k=0; k<j; k++) {
             if(inputNumber == Numbers [k]) {
                 isDuplicate = true;
                 break;
              }
          }

          if(! isDuplicate) {
                Numbers[j++] = inputNumber;
           }
      //End of for statement 
      } 

      System.out.println("The number of distinct values is " + Arrays.toString(Numbers)); 
  //end of main method 
  } 
//end of Class
}

如何在每个方面添加注释
