Hello All,
I am facing a unique issue 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.
Thanks
Neha
