The package gets posted to the comprehensive R archive (CRAN) at intervals, each such posting preceded a thorough test. In general, each new push to CRAN with new function(s) will update the second term of the version number, e.g. 1.2.0 to 1.3.0. Updates only to the code of existing functions increment the third term of the version number, e.g. 1.2.0 to 1.2.1.

Internal datafarames

Internal datafarames are contained in the R/sysdata.rda of the source code, used in the R package functions but not accessible to the user.

• ktx.kdpi_mapping_table - contains data with mapping KDPI and KDRI reported by OPTN for the years 2014-2024
• ktx.kdpi_coefficients - contains data with coefficients used by OPTN for the calculation (KDRI scaling factor, chances of hypertension and diabetes in case if they were unknown for donor, etc)

External datafarames
