plot.dendrogram中的挂起参数不起作用（说[“ hang”不是图形参数]）]]

Question

更新到R版本3.6.1（并更新了所有软件包之后，我再也无法将hang参数与plot.dendrogram结合使用：

data(mtcars)
hc <- hclust(dist(mtcars))
plot(hc) # works as expected

den <- as.dendrogram(hc)
plot(den) # it works
plot(den, hang=0.01) # gives bunch of warnings:
# Warning messages:
# 1: In plot.window(...) : "hang" is not a graphical parameter
# 2: In plot.xy(xy, type, ...) : "hang" is not a graphical parameter
# 3: In axis(side = side, at = at, labels = labels, ...) :
#   "hang" is not a graphical parameter
# 4: In axis(side = side, at = at, labels = labels, ...) :
#   "hang" is not a graphical parameter
# 5: In title(...) : "hang" is not a graphical parameter
有关哪里出什么问题的任何提示？

在我更新到R版本3.6.1（并更新了所有软件包之后，我不再可以将hang参数与plot.dendrogram一起使用：data（mtcars）hc

Answer 1

[hang=是as.dendogram的自变量，而不是plot.*的自变量
