Dear all,
please could you advise on a computationally quick way to compare and merge
2 long lists in R;
the lists are of the following type, for example :
<> in list 1 :
chromosome, coordinateA, coordinateB, value1
chromosome, coordinateC, coordinateC, value2,
etc
<> in list 2 :
chromosome, coordinateX, coordinateY, value6
chromosome, coordinateZ, coordinateT, value8,
etc
In the unified list, if coordinateA=coordinateX, and
coordinateB=coordinateY, then we write :
chromosome, coordinateA, coordinateB, value1, coordinateX, coordinateY,
value6,
otherwise, we write the individual values :
chromosome, coordinateA, coordinateB, value1,
chromosome, coordinateX, coordinateY, value6,
thanks,
bogdan
