回复 第1楼 的 676731245：
用ggplot2包
<br />
library(ggplot2)</p>
<p>mydat = data.frame(x=c(1,2,3), y=rep(0,3), labels=c("A","B","C"), size=c(0.5, 0.3, 0.2));</p>
<p>ggplot(mydat) + geom_text(aes(x,y,label=labels,size=size)) + scale_size_continuous(breaks=NULL, range=c(10,25)) + scale_x_continuous(limits=c(0.7,3.2)) + scale_y_continuous(limits=c(-1,1)) + labs(x=NULL, y=NULL)<br />
</p>
顺便推荐一下emacs + ess 编辑 R 代码[s:11]
