How to calculate the percentage/fraction of each value in a row against the maximum row value?
Hi,
For each row in a file, i would like to identify the maximum value and calculate the percentage/fraction of the max for other values in the row.
Then, I would like to print a copy of the file where values above a threshold are replaced with "1" and other values are left as "0".
In the example below, the threshold is >=0.25 (25%)
Any notes on commands much appreciated!
Thank you!!
input file:
9,0,30,0
0,50,100,20
0,10,0,0
10,100,0,50
## fraction of max value##
0.3,0,1,0
0,0.5,1,0.2
0,1,0,0
0.1,1,0,0.5
Therefore, request output (ony assign "1" if >=0.25):
1,0,1,0
0,1,1,0
0,1,0,0
0,1,0,1
