r - ggplot图中带有两个标签的Geom_text

Question

我正在努力添加一个额外的标签，我想添加到我的 ggplot 图中。

这是我的数据集：

Group                   Gaze direction  Counts   Duration
Expert Performers       game table      148      1262.122
Expert Performers       objects table   40       139.466
Expert Performers       other           94       371.191
Expert Performers       co-participant  166      387.228
Non-Performers          game table      223      1137.517
Non-Performers          objects table   111      369.26
Non-Performers          other           86       86.794
Non-Performers          co-participant  312      566.438

这是我正在使用的代码：

ggplot(b, aes(x=Group, y=Gaze.direction))+
  geom_count(mapping=aes(color=Counts, size=Duration))+
  theme_bw()+
  theme(panel.grid.major = element_line(colour = "grey"))+scale_size(range = c(0, 8))+
  scale_colour_gradient(low = "black", high = "gray91")+
  scale_y_discrete(name ="Gaze direction") + 
  geom_text(aes(label=Counts,hjust=-1, vjust=-1))

所需的图表应包含所有数据点的计数数量（它已经存在）以及括号中的持续时间（在图表中标记为红色）。

如果有人知道如何修复我的代码，我将不胜感激。

请发布您的数据作为dput()输出！

你可以试试这个：

library(ggplot2)
b <- data.frame(Group  = c("Expert Performers","Expert Performers","Expert Performers","Expert Performers","Non-Performers","Non-Performers","Non-Performers","Non-Performers"), 
                   Gaze.direction = c("game table","objects table","other","co-participant","game table","objects table","other","co-participant"), Counts = c(148,40,94,166,223,111,86,312), Duration =c(1262.122,139.466,371.191,387.228,1137.517,369.26,86.794,566.438))

ggplot(b, aes(x=Group, y=Gaze.direction))+
  geom_count(mapping=aes(color=Counts, size=Duration))+
  theme_bw()+
  theme(panel.grid.major = element_line(colour = "grey"))+scale_size(range = c(0, 8))+
  scale_colour_gradient(low = "black", high = "gray91")+
  scale_y_discrete(name ="Gaze direction") + 
  geom_text(aes(label=paste("(",Counts,",",Duration,")"),hjust=-1, vjust=-1))

我paste()在geom_text(): label参数中使用了函数，其中实现了您的两个变量值（计数和持续时间）。
