  upcr_col = NULL,
  calcium_col = NULL,
  phosphate_col = NULL,
  albumin_col = NULL
)

Arguments

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.

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)
