无法查看情节（其中=全部）

Question

我有以下代码：

cny <- read.csv(file="CNY % returns.csv", head=TRUE, sep=",")

arimacny <- forecast::auto.arima(x=cny[,2], trace=TRUE, ic="aic")

spec1 <- ugarchspec(variance.model = list(model = "sGARCH", garchOrder = c(1,1), 
 submodel = NULL, external.regressors = NULL, variance.targeting = FALSE), 
 mean.model = list(armaOrder = c(3, 3), include.mean = TRUE, archm = FALSE, arfima = FALSE, external.regressors = NULL, archex = FALSE), 
 distribution.model = "norm")

fit1 <- ugarchfit(spec=spec1, cny, out.sample = 0, solver = "hybrid")

print(ugarchfit(spec=spec1, data=cny))

使用时：

plot(fit1, which=all)

我的石英窗口显示为完全空白。但是，我能够单独绘制每个图表，没有任何问题。

为什么plot(fit1,which=all)功能对我不起作用？
