我知道
this question
,它只是因为某些原因对我不起作用。

我在R基上做了一些工作,找到了特征多项式根并画出了圆。
但我真的很想用
ggplot2
,只是不知道如何。
我的基本R代码是:
library(plotrix)
gdpDiff <- diff(my_df)
m1 = ar(gdpDiff, method = 'mle')
m1$order
m1$x.mean
m1$ar
p1 = c(1, -m1$ar)
r1 = polyroot(p1)
r1
r1Re <- Re(r1)
r1Im <- Im(r1)
Mod(r1)
plot(r1Re, r1Im, asp = 1, xlim = c(min(r1Re), max(r1Re)), ylim = c(min(r1Im), max(r1Im)))
draw.circle(0, 0, radius = 1)
abline(v = 0)
abline(h = 0)
我目前的结果是(4点):
