R Language-time series plotting

Using the R language, draw two graphics in a drawing window, using the layout manager.

1. The commands for drawing autocorrelation and partial autocorrelation graphs are:

> par (pin=c (4,2), Mfrow=c (2,1)) #设置图形大小 (length 4 ", Height 2"), divided into 2 rows and 1 columns

> Layout (Matrix (c (1,1,2,2), 2,2,byrow=true)) #将绘图区分成4个单元格, 1th, 2 is a row, 3rd, 4 is a row.
> layout.show () #显示布局

> ACF (C2) #自相关图
> pacf (C2) #偏自相关图

The drawing effect diagram is:

2, only calculate not draw the graph

>ACF (C2,plot=false)

3. Draw time series on a graph, ACF (autocorrelation), PACF (partial autocorrelation) diagram
> Layout (Matrix (c (), 3,1,byrow=true), Height=c (1,1,1)) #设置绘图窗口布局, three rows, one column per row, height per row, width not set, 100%
> layout.show () #用于显示布局

> Plot (x1,type= "L") #绘制时间序列

> ACF (x1) #绘制acf图
> PACF (x1) #绘制pacf图
To draw an effect diagram:
