如何使用R中的forestplot包在forestplot中将行压缩在一起

install.packages("forestplot")

library(forestplot)

# 导入数据
data <- read.csv("data.csv")

# 处理数据
forest_data <- data.frame(
  row = c("行1", "行2", "行3"),  # 行名称
  estimate = c(0.5, 0.8, 1.2),  # 效应大小
  lower = c(0.3, 0.6, 1.0),     # 置信区间下限
  upper = c(0.7, 1.0, 1.4)      # 置信区间上限
)

# 绘制forestplot
forestplot(
  mean = forest_data$estimate,    # 效应大小
  lower = forest_data$lower,      # 置信区间下限
  upper = forest_data$upper,      # 置信区间上限
  title = "Forest Plot",          # 图表标题
  xlab = "Effect Size",           # x轴标签
  is.summary = c(TRUE, FALSE),    # 是否为汇总行
  clip = c(0, 2),                 # y轴范围
  col = fpColors(box="black", lines="black"),  # 颜色设置
  zero = 1,                       # 零线位置
  cex = 0.8                      # 文本大小
)
