Hello Monks, I have two files, file 1 is 3 fields and many rows and looks like:
1 19002930 0.74 1 19002931 -0.12
And file 2 has 10,002 fields and many rows and looks like:
1 19002930 0.84 0.12 0.94 ... 1 19002931 0 -.20 .12 ...
I would like to compare each field starting with field 3 from file 2, to field 3 in file 1. If fields 1 and 2 in files 1 and 2 match, and If the value in file 2 is greater than or equal to field 3 from file 1, I would like to push that value onto an array. The output would look like:
1 19002930 0.84 0.94 ... 1 19002931 0 .12
I have an R script that does this, but R takes way too long. Would someone be able to help me out?
