Hi i'm trying to make a loop, concatenating the columns of the data_0 file
one at a time
do while i<4
q = data_0[.,1]~data_0[.,i]
it's not working and i don't know why !
can you help me ?
I see a couple of problems:
- All GAUSS statements need to end with a semi-colon. You are missing semi-colons on several of the lines
- Your loop keeps running until i is greater than 4, but i is assigned to be equal to 2 (1 + 1) each time in the loop, so the loop will keep running forever.
I would also change it to use a for loop instead. Like this:
//counter(start, stop, step_size) for i(1, 4, 1); q = data_0[.,1] ~ data_0[.,i]; endfor;
If q will always be a matrix with 2 columns in this loop, then I would change it to something like this:
//Make 'q' a matrix with 2 columns q = data_0[.,1 2]; for i(1, 4, 1); //Swap out the 2nd column q[.,2] = data_0[.,i]; endfor;
which should be faster.
