关联规则错误

Question

我试图使用以下代码来使用 "arules" 包的关联规则。

数据link (http://archive.ics.uci.edu/ml/datasets/Adult)

library(Matrix)
library(arules)
adult<-read.table("adult.data.txt", sep = ",")
colnames(adult)<- c("age","workclass","fnlwgt","education","education-num","marital-status","occupation","relationship","race","sex","capital-gain","capital-loss","hours-per-week","native-country","Probability for the label")

移除

adult[["fnlwgt"]] <- NULL
adult[["education-num"]] <- NULL

组

adult[["age"]] <- ordered(cut(adult[["age"]], c(15,25,45,65,100)), labels = c("Young", "Middle", "Older", "Senior"))

adult[[ "hours-per-week"]] <- ordered(cut(adult[[ "hours-per-week"]], c(0,25,40,60,168)),labels = c("Part-time", "Full-time", "Over-time", "VeryHigh"))

adult[[ "capital-gain"]] <- ordered(cut(adult[[ "capital-gain"]], c(-Inf,0, median(adult[["capital-gain"]][adult[["capital-gain"]]>0]), Inf)), labels = c("None", "Low", "High"))
adult[[ "capital-loss"]] <- ordered(cut(adult[[ "capital-loss"]], c(-Inf,0, median(adult[["capital-loss"]][adult[["capital-loss"]]>0]), Inf)), labels = c("None", "Low", "High"))

adult2 <- as(adult, "transactions")
rules <- apriori(adult2, parameter = list(supp = .5, conf = .85, target = "rules", minlen=2))

错误

IS = interestMeasure(rules, method = "cosine", adult2, reuse = FALSE)

但是，我收到以下错误。我也尝试了其他一些 "methods" 但同样的错误。我将不胜感激任何类型的建议。

Error in .local(x, transactions, ...) : transactions missing. Please specify the transactions used to mine the itemsets! In addition: Warning message: In interestMeasure(rules, method = "cosine", adult2, reuse = FALSE) : interestMeasure: parameter method is now deprecated! Use measure instead!

Answer 1

在对包 arules 一无所知的情况下，使用 "measure" 而不是 "method" 如下行应该可行（基于帮助页面）

IS = interestMeasure(rules, measure = "cosine", adult2, reuse = FALSE)
