profileCI 1.1.1

CRAN release: 2026-01-26

Bug fixes and minor improvements

  • When the argument epsilon to profileCI() is negative, monotonic cubic spline interpolation is now used instead of quadratic interpolation. Quadratic interpolation could fail in some cases.
  • In the documentation of the argument object to profileCI() it is emphasized that the parameters in the fitted model object must have names.
  • Fixed bugs in profileCI-internal.R to avoid storing some slightly incorrect parameter values near the confidence limits in the attribute "for_plot" in the returned object.

profileCI 1.1.0

CRAN release: 2025-07-11

New features

  • An argument flat has been added to profileCI() to deal with cases where one or both of the limits is (minus or plus) infinity because the profile log-likelihood fails to drop below the level that defines the confidence interval.
  • Arguments lb and ub have been added to profileCI() to place respective lower and upper bounds on the interval over which profiling takes place.
  • A logLikFn method has been added for objects inheriting from class nls and an example added to the documentation of profileCI().

Bug fixes and minor improvements

  • The argument optim_args actually works now! Thank you to Jakob Madsen (#1).
  • An explanation of the creation of coef and vcov methods has been added to the description of object in the profileCI() documentation.
  • Arguments to the user-supplied log-likelihood function are extracted explicitly to simplify the code and avoid potential argument matching issues.
