The inspiration for {card} was to create useful
functions and analytical approaches in computational neurocardiology,
with a on electrocardiography and epidemiology.
The areas of focus of this package are the following:
You can install the released version of {card} from CRAN with:
install.packages("card")And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("shah-in-boots/card")The intent for card is to assist in the analysis of
cardiovascular and epidemiological data, with a focus on
cardiac-specific datasets and data types.

allows internal flexibility for modeling heuristics and improved
efficiency. For the user, it also allows standard modeling
tools/approaches, and a flexible user interface that accounts for
individual/population analysis and single/multiple component
analysis.
There are other cosinor models available in R, however
they do not allow for simple multiple-component or individual/population
analysis in a method that is tidy (for both tidyverse and
tidymodels approaches).
