Hello,
My data is "study.txt":
"Not A" "A"
"Mathematics" 80 15
"Physics" 32 24
"Biology" 18 29
I want to transform this data into with column names 'course' and 'A':
course A
1 Mathematics 1
2 Mathematics 1
.. ...... ..
80 Mathematics 1
81 Mathematics 0
... ............ ...
95 Mathematics 0
96 Physics 1
... ............ ...
127 Physics 1
128 Physics 0
... ............ ...
151 Physics 0
etc.
How should I do it? So this data frame will consist from 198 rows.
Thank you very much.
kind regards,
T. Bal
