请看如下代码plot(merge(as.zoo(USMacroG[,"consumption"]), fitted(cons_lm1),fitted(cons_lm2), 0, residuals(cons_lm1),
residuals(cons_lm2)), screens = rep(1:2, c(3, 3)),
lty = rep(1:3, 2), ylab = c("Fitted values", "Residuals"),
xlab = "Time", main = "")
上面的screens参数经过试验发现是分割图形的，具体怎么用，希望精通的同学指点

screens: factor (or coerced to factor) whose levels specify which graph each series is to be plotted in. screens=c(1,2,1) would plot series 1, 2 and 3 in graphs 1, 2 and 1. If not specified then 1 is used if plot.type="single" and seq_len(ncol(x)) otherwise.

其他参数可以参考：http://svitsrv25.epfl.ch/R-doc/library/zoo/html/plot.zoo.html
