Question

R中的forestplot包不允许将多种颜色分配给线或框。但是，它适用于文本。 fpColors函数指出以下内容： “如果在森林图中每行有多个值，则可以将颜色设置为矢量，其中第一个值代表第一行/框，第二个代表第二行/框，依此类推。矢量仅对框有效\和行选项。”

请参见以下示例：

library(forestplot)
# Cochrane data from the 'rmeta'-package
cochrane_from_rmeta <- 
structure(list(
    mean  = c(NA, NA, 0.578, 0.165, 0.246, 0.700, 0.348, 0.139, 1.017, NA, 0.531), 
    lower = c(NA, NA, 0.372, 0.018, 0.072, 0.333, 0.083, 0.016, 0.365, NA, 0.386),
    upper = c(NA, NA, 0.898, 1.517, 0.833, 1.474, 1.455, 1.209, 2.831, NA, 0.731)),
    .Names = c("mean", "lower", "upper"), 
    row.names = c(NA, -11L), 
    class = "data.frame")

tabletext<-cbind(
c("", "Study", "Auckland", "Block", 
  "Doran", "Gamsu", "Morrison", "Papageorgiou", 
  "Tauesch", NA, "Summary"),
c("Deaths", "(steroid)", "36", "1", 
  "4", "14", "3", "1", 
  "8", NA, NA),
c("Deaths", "(placebo)", "60", "5", 
  "11", "20", "7", "7", 
  "10", NA, NA),
c("", "OR", "0.58", "0.16", 
  "0.25", "0.70", "0.35", "0.14", 
  "1.02", NA, "0.53"))

forestplot(tabletext, 
       cochrane_from_rmeta,new_page = TRUE,
       is.summary=c(TRUE,TRUE,rep(FALSE,8),TRUE),
       clip=c(0.1,2.5), 
       xlog=TRUE, 
       col=fpColors(box=c("darkblue", "darkred"),line=c("darkblue", "darkred"), text=c("darkblue", "darkred"), summary="royalblue"))
