在此处输入图像描述我想在我的情节中添加百分比,但我不知道我的问题是什么,这是我的代码:

    install.packages("ggmosaic")
  library(ggmosaic)
  library(tidyr)
  library(dplyr)
  library(ggplot2)
  library(vcd)
  M = as.table(as.matrix(healthcare[,-1]))
  View(M)
  names(dimnames(M)) = c("ever married","work type")
  labs <- round(prop.table(M))
  mosaic(M, pop = FALSE)
  labeling_cells(text = labs, margin = 0)(M)
  a<-c("blue","red")
