dataformat

问题 I tried to search other posts in R related to this, but did not find duplicated questions(at least to my efforts). I know I need a priori function in library("a rules") though. I have a large array file A that each row is a list user1: [1,2,3,4] # [1,2,3,4] is the itemList purchased by this user user2: [4] ................

Closed 3 years ago . I'm in the process of compiling data from different data sets into one data set for analysis. I'll be doing data exploration, trying different things to find out what regularities may be hidden in the data, so I don't currently have a specific method in mind. Now I'm wondering if
