Hi, I have a data file with n columns and r row. The first 3 columns and the first 5 rows are:
2 3 1 1 6 X 4 0 X X 8 X 5 X 5 The "X" means missing. How could I write a script to calculate the average by column and replace "X" with the average? The output should be like: 2 3 1 1 6 3 4 0 3 3 8 3 5 4.25 5 For column 1, the counts excluding "X" is 4 with sum=12. So the average for column 1 is 3. For column 2, the counts excluding "X" is 4 with sum=17. So the average for column 2 is 4.25. For column 3, the counts excluding "X" is 2 with sum=6. So the average for column 3 is 3.
