My script is the following:
library(metafor)
yi<-c(-0.1, 0.2, 0.3, 0.4)
sei<-c(0.4, 0.2, 0.6, 0.1)
vi<-sei^2
studi<-c("A", "B", "C", "D")
eventi.c<-c(10, 5, 7, 6)
n.c<-c(11, 34, 25, 20)
eventi.a<-c(2, 7, 6, 5)
n.a<-c(11, 35, 25, 15)
dfs<-rma(yi, vi, method="DL")
dfs
windows(height=6, width=10, pointsize=10)
windowsFonts(B=windowsFont("Bookman Old Style"))
forest.rma(dfs, slab=studi, xlim=c(-15, 10), ilab=cbind(eventi.c, n.c,
eventi.a, n.a), ilab.xpos=c(-9.5, -8, -6, -4.5), cex=1.2, at=c(-2, -1, 0, 1,
2), family="B", xlab="Hazard Ratio (log scale)", mlab="Random Effects
Model", efac=5, col="red", border="red")
text(-10, -1.3, paste("Heterogeneity: I-squared=", paste(paste(round(dfs$I2,
2), "%", sep=""), paste("p", round(dfs$QEp, 4), sep="="), sep=", "),
sep=""), font=4, cex=1.2, family="B")
op<-par(cex=1.2, font=2, family="B", oma=c(0.5, 0.5, 0.5, 0.5), mar=c(0.5,
0.5, 0.5, 0.5))
text(x=c(-9.5, -8, -6, -4.5), 6, c("Events", "N", "Events", "N"), cex=1.2 )
text(c(-8.7, -5.5, 8), 6.5, c("S", "A", "Log"))
text(-15, 6, "Trials", pos=4)
text(10, 6, "Hazard Ratio [95% CI]", pos=2)
par(op)
Even if I have specified "col="red", border="red"", color of squares and
diamond rests black! Why?
