一页多图，首先设定par(),
例如 par(mfrow=c(2,3)) 一个图版显示2行，3列。
之后按照常规作图就可以了。
如果在原有的图形上添加新的内容，如果用plot(),则可以选 plot(x, add=TRUE)
另外，低水平的绘图函数可以直接在图形上添加元素，如 points(), lines(),等等

par(mfrow=c(4,2))

x<-seq(1:10)y1<-rnorm(10)

y2<-rnorm(10,mean=2,sd=1)

y3<-rnorm(10,mean=3,sd=1)

y4<-rnorm(10,mean=4,sd=1)

y5<-rnorm(10,mean=5,sd=1)

y6<-rnorm(10,mean=6,sd=1)

y7<-rnorm(10,mean=7,sd=1)

y8<-rnorm(10,mean=8,sd=1)

plot(x,y1,type='o', lty=1, main="I want this title is to be scaled down(resized)", cex.main = 0.3)

plot(x,y2,type='o', lty=2, main="I want this title is to be scaled down(resized)", cex = 0.1)

plot(x,y3,type='o', lty=3, main="I want this title is to be scaled down(resized)", cex.axis = 0.1)

plot(x,y4,type='o', lty=4, main="I want this title is to be scaled down(resized)")

plot(x,y5,type='o', lty=5, main="I want this title is to be scaled down(resized)")

plot(x,y6,type='o', lty=6, main="I want this title is to be scaled down(resized)")

plot(x,y7,type='o', lty=7, main="I want this title is to be scaled down(resized)")

plot(x,y8,type='o', lty=8, main="I want this title is to be scaled down(resized)")
