Agreement on prefix of function names and internal data frames

nephro. - related to nephrology in general
ktx. - related to kidney transplantation
hd. - related to hemodialysis
pd. - related to peritoneal dialysis
egfr. - related to equations for calculation of estimated glomerular filtration rate
epi. - related to epidemiology in general
service. - service functions or internal purposes of the package (data check, etc)
matrix. - functions for working with matrix

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

• ckd.data - contains synthetic data for eGFR calculation in 1000 adults and 1000 children.
  
• ktx.data - contains data for 10 kidney transplant patients.
