Dear,
I am using R I'm trying to identify and remove columns and rows in a data
frame that are has elements equals. For example in dataframe below. The
columns 1, 2,3,4,5 ,6 and 10 (file1) has elements equal then should be
removed. How can I ask R to remove those columns with same elements in new
dataframe (file2) to result a matrix as follows:
file1
1 0 2 2 1 1 5 1 1 1
1 0 2 2 1 1 5 1 1 1
1 0 2 2 1 2 5 2 2 1
1 0 2 2 1 1 5 1 1 1
1 0 2 2 1 0 5 0 2 1
1 0 2 2 1 1 5 1 0 1
file2
1 1 1
1 1 1
2 2 2
1 1 1
0 0 2
1 1 0
After I need to know which ones names of columns are remove = 1, 2,3,4,5 ,6
and 10.
Similarly this is I need to check for rows in file2. To remove rows and
identify all that elements equal.
The final dataframe is:
file3
0 0 2
1 1 0
row names removed = 1,2,3 and
Thanks and Regards
