card {development version}

Next Steps

• cosinor() to be expanded upon to include prediction, and integration into the tidymodels approach in the parsnip package
  • Evaluation of plotting functions for cosinor models
  • Confidence interval methods to be improved upon
• Population cosinor analysis to be reworked for correct predictions and confidence interval estimates

Deprecations

• The circadian-focused features are being deprecated in this upcoming release. The goal is to position functions in the appropriate package, with the key cosinor() functions to move to a separate package in a future release.

• The longitudinal event functions are being moved to a separate package to make maintenance more straightforward.

card v0.1.1

Updates

• cosinor() now has a stable population mean cosinor option with appropriate confidence intervals

• procedure_codes() has the latest ICD10 codes, as of 11/2023, and are included in the package

Next steps

• Adding additional data analysis tools for cardiology data (including catheterization and echocardiogram data)

Deprecations

• The circadian-rhythm features have been deprecated and recurrent data features have been removed

• The cosinor() functions will be updated to be more customizable and more efficient, however will be moving to a separate package by v0.2.0

card v0.1.0

Bugs

• cosinor() unable to run on certain models based on y values

Features

• cosinor_features() allows for assessing global/special attributes of multiple component cosinor analysis
• ggcosinor() is now functional for single and multiple component analysis
• Sequential model building can be performed with build_sequential_models(), however it is in a list format and will likely be updated to be more “tidy” in the future
• Confidence interval methods now work for population-mean cosinor, including summary function
• ggpopcosinor() can show the cosinors for individuals across a population, along with mean and predicted cosinor
• ggcosinor() accepts single models
• print.cosinor() and plot.cosinor() functions added
• cosinor_zero_amplitude() test added, works for individual cosinor.
• Population-mean cosinor analysis is added. cosinor() now takes the argument of for individuals. The individual cosinor methods generally work, but may not yet be accurate.
• Circadian rhythm analysis has also created an initial family of functions that will work to simplify the process of analyzing 24-hour data. The circ_compare_groups() helps to summarize circadian data by an covariate and time. This is visualized using ggcircadian(). Also includes the ggforest() to create forest plots of odds ratios. This is dependent on the circ_odds() function to generate odds ratios by time.
• An important regression function, built with the hardhat package from tidymodels, cosinor() introduced as a new function to allow for diagnostic analysis of circadian patterns. Although the algorithm is well known, having an implementation in R allows potential diagnostics. This includes the ggcosinorfit() allows for assessing rhythmicity and confidence intervals of amplitude and acrophase of cosinor model. Basic methods for assessing the model, such as print, summary, coef, and confint currently function.
• Recurrent events can now be analyzed using a powerful function called recur_survival_table(), which allows for redesigning longitudinal data tables into a model appropriate for analysis. It is built to extend survival analyses. The recur_summary_table() function allows for reviewing the findings from recurrent events by category to help understand event strata.
• The circ_sun() function allows for identifying the sunrise and sunset times based on geographical location. This is intended to couple with the circ_center() function to center a time series around an event, such as sunrise. A vignette has been added to review this data.
