Hello,
I have a matrix
animal time A01 A02
A d0 -5.4 2.7
A d112 4.6 5.9
A d224 3.9 6.3
B d0 7.1 5.6
B d112 1.5 3.2
B d224 2.9 3.6
C d112 3.7 5.8
C d0 7.1 NA
C d224 4.2 5.7
I have three animal A, B, C. Each animal have two measurements(A01 and A02)
at three different time points (d0, d112 and d224). I'd like to calculate:
animal A:
A01 at d112 (4.6) - A01 at d0 (-5.4)
A01 at d224 (3.9) - A01 at d0 (-5.4)
A02 at d112 (5.9) - A02 at d0 (2.7)
A02 at d224 (6.3) - A02 at d0 (2.7)
Same for animal B and C
I really appreciate your help.
