How is it possible to determine the number of estrous cycles in dogs when the occurrence of the cycle is given.

For instance, when the determinants of the cycle is given by DI,PR,ES,ME,S,P where DI=diestrus,PR=Proestrus,ES=estrus,ME=metestrus,S=sperm,P=plug.

The occurrence of estrus is only that matters and the cycle is given by EST DI DI DI MET EST -- here the length of the cycle is 5 until the occurrence of next estrus.

A cycle is calculated from one estrus to another estrus. The length of the cycle is the period until next estrus occurs which is 5 in the above case.

How do I write a code to calculate this in Statistics. The endpoint is to calculate the number of cycles and length of each cycle.

The output has to look like this:

animal_id cycle1 cycle2 cycle3

101 5 3 2

102 2 3 1

103 3 1 2
