Hi there
I have the variables
Pid, x, y, t, d
For 1000 participants, and there are many observations for each
participant.
I'm using an archaic program that uses data in the format:
Pid
X,y
X,y
X,y
END
Pid
X,y
X,y
END
And so on.
I would think that I need to :
loop through for each pid
identify the value of pid
write this value to an outfile
loop through all observations of current pid
extract values for x and y
write x and y values to outfile
write "end" into outfile
I tried this logic, but I can't seem to append info to the outfile...
any ideas?
Cheers
Dan
