epocakir 0.9.6

Initial CRAN submission

Improvements

• Added vignette Introduction to epocakir with basic usage examples
• Updated README
• Added sample clinical_obvs to demonstrate utility functions

Bug fixes

• Exported conversion_factors, similar to ordered factors like aki_stages
• Corrected mis-spelled words

epocakir 0.9.5

Added sample data and better examples

Improvements

• Added sample data based on test data
• Cleaned up code comments
• Added examples to methods

Breaking Changes

• Renamed aki() to aki_staging() for more consistent method names

Bug fixes

• Fixed bug when n < m for combn() in combn_changes()
• Changed methods from method.default() to method.data.frame() to prevent infinite recursion on incorrectly specified function arguments

epocakir 0.9.0

Improved high level API functions

Improvements

• Wrote new combined eGFR() function that automatically selects the appropriate eGFR_method() formula to use
• Wrote new combined aki() function that automatically calculates AKI based on all criteria and determines most severe stage
• Added additional tests including warnings

Breaking Changes

• Added No AKI and No Albuminuria to stages ordered factors to prevent users have to handle NAs mixed with ordered factors

Bug fixes

• Fixed bug in eGFR_internal() where it was looking for !is.na(black) to select eGFR_adult_SCysC(), when black was not required

epocakir 0.8.0

Initial full-featured release of epocakir methods

Improvements

• Wrote aki_SCr() function
• Methods now include aki_bCr, aki_SCr, aki_UO, anemia, eGFR_adult_SCr, eGFR_adult_SCysC, eGFR_adult_SCr_SCysC, eGFR_child_SCr, eGFR_child_SCr_BUN, eGFR_child_SCysC, GFR_staging, Albuminuria_staging_AER, Albuminuria_staging_ACR and combn_changes

Bug fixes

• Used tibble::tibble() instead of data.frame() to prevent issue with stringsasfactors difference between R 3.x and R 4.x
• Fixed sorting error in `aki_UO()

epocakir 0.7.0

Re-wrote methods for consistency

Improvements

• Removed duplicate GFR_staging() code
• Stricter expect_identical() instead of expect_equal() assertions
• Rewrote anemia() to make method selection consistent with other functions

Bug fixes

• Consistent parameter naming

epocakir 0.6.0

Re-wrote all eGFR functions as S3 methods

Improvements

• Wrote eGFR_adult_SCr, eGFR_adult_SCysC, eGFR_adult_SCr_SCysC, eGFR_child_SCr, eGFR_child_SCr_BUN, eGFR_child_SCysC methods

Breaking changes

• Instead of individual functions, use methods for all low-level functions
• Renamed functions to snake_case, e.g. eGFR.adult.SCr_SCysC to eGFR_adult_SCr_SCysC

epocakir 0.5.0

Improved handling of function arguments

Improvements

• Changed from forcats::fct_c to vctrs::vec_c for improved NA handling (https://github.com/tidyverse/forcats/issues/250)
• Wrote aki_bCr() method
• Allow symbols to be passed to methods

Breaking changes

• Added version numbers to dependencies

epocakir 0.4.0

Added testing and additional utility functions to package

Improvements

• Wrote as_metric()
• Additional KDIGO guidelines (https://kdigo.org/guidelines/) added
• Added Albuminuria levels as an ordered factor

Bug fix

• Correctly use pmin instead of min in eGFR calculation

epocakir 0.1.5

dplyr compatible functions

Improvements

• Proper handling of column names using dplyr programming (https://dplyr.tidyverse.org/articles/programming.html)
• Wrote aki_bCr calculation as part of aki() staging
• Wrote .dob2age() function to calculate a patient's age
