用四行命令可以画出两个系列的柱状图
read.table("cons_count.txt",header=T)->z
barplot(rbind(z[,2],z[,3]),names.arg=z[,1],col=c("red","green"),width=c(0.1,0.1),space=c(0,1),beside=T,border=NA,ylim=c(0,0.25))
legend("topleft",c(colnames(z)[2],colnames(z)[3]),fill=c("red","green"),bty="n",border=NA)
box()
另外，还有一个博文http://abbypan.blogspot.hk/2009/04/r.html 介绍的更详细一点。
