migrate 0.5.1

Bug Fix

• Remediates issue where migrate() would fail if values of time argument had overlapping characters (i.e., “T1” and “T100”)
  • migrate() now throws a warning if the argument passed to time is a character-type column

migrate 0.5.0

Enhancements

• A new fill_state argument to migrate() has been introduced, allowing users to migrate IDs that only exist at a single timepoint to a new or existing state
• Errors, warnings, and messages (which were previously handled exclusively by {rlang}) output in the console have been improved via the use of {cli}

Bug Fixes

• Resolves an error that was thrown when attempting to coerce a state argument of type character to type factor

Technical Changes

• The date argument in migrate() has been fully deprecated (replaced by time argument in v0.4.0)
• The {magrittr} pipe %>% has been replaced by the native pipe |> that was introduced in R 4.1. Due to this, the minimum R version required to install {migrate} has been bumped to R 4.1. Accordingly, {magrittr} was removed from Imports.
• {cli} and {glue} have been added as Imports

Miscellaneous

• A {pkgdown} site for the package has been created at https://ketchbrookanalytics.github.io/migrate/
• License has been bumped to 2024, and copyright holder has been changed to Ketchbrook Analytics LLC
• GitHub repository has been transferred from mthomas-ketchbrook to ketchbrookanalytics

migrate 0.4.0

• This release mainly aims to resolve deprecated quasiquotation with dplyr::enquo and (!! var) in favor of the ({{ var }}) syntax.
• This is the first release where we have adequate testing coverage.

Breaking Changes

• The date argument in migrate() has been replaced (renamed) in favor of time

The term date seemed too specific to use in the migrate() function, so it was replaced by the more general term, time. Instead of holding users to using Date-type column variables, this change allows them flexibility to migrate from Time A –> Time B, for example.

Other Features & Improvements

• migrate() has a new verbose argument (logical TRUE/FALSE), which informs the user of the time horizon over which the migration is being calculated:

migrate(
  data = mock_credit,
  id = customer_id,
  time = date,
  state = risk_rating
)
# > === Migrating from: `2020-06-30` --> `2020-09-30` ===
# > ... [output] ...

• {migrate} is now more light-weight: the dependencies on {crayon} & {stringr} have been removed

migrate 0.3.0

• Deprecated rating argument in migrate(), renamed to state
• Added back id argument in migrate()
• Revised mock_credit dataset
• migrate() defaults to percentage migration, instead of absolute

• Improvements to docs
