Hi all,
I have two data sets I want to merge. One has a vector with trap IDs and the vector from the other data set has the number of individuals captured at each trap site. I need to reverse the trap ID's within the trap ID vector in order to match the number trapped. Here is an example of how the vector looks like:
TrapID
A01
B01
C01
A02
B02
C02
A03
B03
C03
I need the vector to look like this
C01
B01
A01
C02
B02
A02
C03
B03
A03
I can do the first chunk using this code:
rev(TrapID[seq(1, 3)])
I've tried several versions of this code including doing a for loop where I ran each sequence through, but it never worked. Any thoughts as to how I can do the reversal of a sequence within my vector???
