to remove columns and rows
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
