Perform unit and code conversions used by KFRE helpers.

Usage

perform_conversions(
  df,
  reverse = FALSE,
  convert_all = FALSE,
  upcr_col = NULL,
  calcium_col = NULL,
  phosphate_col = NULL,
  albumin_col = NULL
)

Arguments

df: Data frame with source columns to convert.
reverse: Logical, reverse the conversion if TRUE.
convert_all: Logical, convert all known columns if TRUE.
upcr_col: Column name for urine protein creatinine ratio.
calcium_col: Optional column for serum calcium, mg/dL.
phosphate_col: Optional column for serum phosphorus, mg/dL.
albumin_col: Optional column for serum albumin, g/dL.

Value

A data frame with converted columns.

Examples

df <- data.frame(
  upcr = c(100, 400),         # mg/g (or g/g scaled accordingly)
  albumin = c(40, 38),        # g/L
  phosphorous = c(1.1, 1.3),  # mmol/L
  calcium = c(9.2, 8.8)       # mg/dL
)
perform_conversions(df)
#>   upcr albumin phosphorous calcium
#> 1  100      40         1.1     9.2
#> 2  400      38         1.3     8.8
