Hi,
I'm processing a data file with the following structure:
#index  time distance
1  10  500
1  15  300
1  23  215
1  34  200
2  5    400
2  13  340
2  15  210
3  10  200
3  12  150
3  16  30
etc

My intention was to generate line plots for the datapoints using their index
to group the elements. I managed to get something to work using a for loop
and some conditionals but I was wondering if there is a better way using
factor or some other R method? Any help improving my R coding would be
greatly appreciated!
Thanks
Jonathan
