有这个 R 语句：
itemsets = apriori(data, parameter=list(support=0.05, confidence=0.5))
plot(itemsets, method="graph",
control=list(type="items"))
我怎样才能改变我的情节的颜色？我尝试插入“col”，但不允许我这样做，因为我收到以下错误：
Error in i.parse.plot.params(graph, list(...)) :
Unknown plot parameters: col
谢谢
使用edgeCol和nodeCol：
library("arulesViz")
data(Groceries)
rules <- apriori(Groceries, parameter=list(support=0.005, confidence=0.5))
plot(rules, method="graph",
control=list(nodeCol="yellow", edgeCol="blue", type="items"))
好吧，试试这个——
itemsets = apriori(data, parameter=list(support=0.05, confidence=0.5))
plot(itemsets, method="graph",
control=list(type="items", col="red"))
干杯!
