shell, read table and write the value for each factor to output
Hey guyz,
I have a table like this:
1 A=#;B=#;C=# |
2 A=#;C=#;D=#;E=#;E=# |
3 B=#;B=#;B=#;D=# |
# are just some numbers. I want to have the output like this:
* 1 2 3 |
A # # NA |
B # NA # |
C # # NA |
D NA # # |
E NA # NA |
So basically, I wanna know in each of the rows in my input (which gonna be the columns in output) what is the number for each factor (A,B,C,...). sometimes there are repeating of one factor which I like to take the maximum number in that case. And sometimes the factor is missing which it turns NA in corresponding cell in output.
There are not the same number of factor in each row which makes it problematic.
Can anyone help me with this?
Thanks in advance
