Hello All, I am facing a unique problem and am unable to find any help in R help pages or online. I will appreciate your help for the following problem: I have 2 data-frames, samples below and there is an expected output
R Dataframe1: C1 C2 C3 C4...... CN R1 0 1 0 1 R2 1 0 1 1 R3 1 0 0 0 . . . RN U Dataframe2 : C1 C2 C3 C4...... CN U1 1 1 0 1 U2 1 1 1 1 Expected Output: U1 satisfies R1, R3 U2 satisfies R1, R2, R3 So this is a comparison of dataframes problem, with a subset dimension. There are 2 dataframe R and U. column names are same. There are certain columns belonging to each row in dataframe 1, denoted as 1s, while there are certain cols to each U denoted as 1s in each URow in dataframe2. I have to find relationships between Rs and Us. So i start with each U row in U dataframe (lets say U1 row) and try to find all the rows in R dataframe, which are subset of U1 row. I cant find a way to compare rows to see if one is subset of another....what can I try, any pointers/ packages will be great help. Please help.
