vector of minimum lifespans for each individual.
input a matrix or a single-columned data.frame of capture histories. It will return a vector of minimum lifespans for each row
This function computes the mimimum lifespans given a capture history. This is computed as the first day seen subtracted by the last day seen. For example, an individual with the capture history of "1001" would have a minimum lifespan of 3; "1110" = 2; "1010" = 2, "01000001" = 6 etc. See examples.
