这个不用包，就可以实现——
par(mar=c(5,5,4,5)+0.1)
bar <- barplot(y1,xlim=c(0,5),ylim=c(0,100),ylab="Weight (kg)",col="blue",col.axis="blue",col.lab="blue")
mtext(x,side=1,line=1,at=bar,col="black")
mtext("Name",side=1,line=3,col="black")
par(new=T)
plot(bar,y2,axes=F,xlim=c(0,5),ylim=c(100,190),xlab="",ylab="",col="red",type="b")
axis(4,col="red",col.ticks="red",col.axis="red")
mtext("Heigth (cm)",side=4,line=3,col="red")
dev.off()
这个是用plotrix 做的，你也可以参考下——
d <- data.frame(name=c("zhao","qian","sun","li"),
weight=c(62,58,79,60),
height=c(178,169,180,173))
x <- d$name
y1 <- d$weight
y2 <- d$height
library(plotrix)
xpos <- 1:4
twoord.plot(xpos,y1,xpos,y2,xlim=c(0,5),lylim=c(0,100),rylim=c(100,190),
lcol=4,rcol=2,
xlab="name",ylab="Weight (kg)",rylab="Height (cm)",type=c("bar","b"),
xticklab=x,halfwidth=0.2)
dev.off()
