Both functions return a capthist object with one row for each unique capture history (including covariates). The individual covariate `freq' records the number of instances of each unique history in the input.
Arguments

secr capthist object
Details
Although squeeze may be applied to spatial capthist objects, the
effect is often minimal as most spatial histories are unique.
The `freq' covariate is used by openCR.fit to weight summaries and likelihoods. It is currently ignored by secr.fit.
