rprev 1.0.4

Made changes to account for the upcoming stringsAsFactors = FALSE default argument to data.frame() in R 4.0 so that the package is backwards compatible.

rprev 1.0.3

Change to unit test to allow for a tolerance when comparing floating points and a fix for a warning thrown from r-devel.

rprev 1.0.2

Hotfix to address new sample implementation forthcoming in R 3.6.0. Currently the warning is being suppressed, but the unit tests will be updated once these changes have been implemented in stable R.

rprev 1.0.1

Minor documentation fixes, with the main one being correcting the name of the Diagnostics vignette.

rprev 1.0.0

Major overhaul to the API with non-backwards compatible changes. The primary change is that both the incidence and survival models are now specifiable, in contrast to the previous version which forced a homogeneous Poisson process incidence model and a Weibull survival model that uses age and sex as covariates. These models are retained as defaults, but the user can provide custom objects for both these processes, as documented in the User Guide.

A number of small basic functions mostly relating to diagnostics have been removed to condense the API.

See the User Guide vignette for examples of the new parameterisation of prevalence and general documentation.

rprev 0.2.3

Renamed raw_incidence to yearly_incidence

This function has been renamed to be more descriptive of what the function actually does, and reparameterised to allow the user to specify the ending date of the time interval of interested instead. raw_incidence is still included but it throws a deprecated warning and suggests the use of yearly_incidence

Renamed determine_registry_years to determine_yearly_limits

The original function name isn’t very descriptive for what it does (provides the yearly end points of a specific time interval) and so have renamed it to better reflect its purpose. determine_yearly_limits has a slighlty different argument list to determine_registry_years to allow for the specification of the closing date in the interval rather than the opening.


rprev 0.2.2

Bug hotfix.

rprev 0.2.1

The posterior age distribution, returned from prevalence as in the simulated object, is now stored in the format of a nested list rather than a matrix as before. The first dimension of the list corresponds to each sex (if applicable), the next indexing the number of years of simulated cases, and the final corresponds to the bootstrap samples. The final level comprises a vector holding the ages of the simulated cases which are still contributing to prevalence at the index date from the corresponding sex, year, and bootstrap sample number.

rprev 0.2.0

Minor bug fixes and a slight change to the parameterisation of prevalence:

rprev 0.1.0

First release of the package, working with all features necessary to provide estimates of point prevalence. Issues which we’d like to address in future releases are:
