My file is composed of several females on which we followed the maturation of the eggs by ultrasound. We therefore have several dates with the size of the eggs for 36 females.
Basically this is what the table looks like
Date Female Egg size
05/01/2020 a 0.2
05/01/2020 b 0.25
06/02/2020 a 0.3
06/02/2020 b 0.36
07/15/2020 a 0.52
07/17/2020 b 0.5
I would like to make a graph by assigning the egg-laying date for each female as day 0 and invert the dates according to the days of maturation.
Approximate example: 07/15 = D0, 06/02 = -D43 and 05/01 = -D74
I have this for 36 femelles with ramdom date
Thanks a lot
