Description Usage Arguments Details Value Author(s) References See Also Examples

Computes estimated creatinine clearance using the Cockroft-Gault formula.

1	crcl.cg(..., scr.mg.dL, weight.kg, age.yr, is.female, scr.umol.L, scr.conversion.factor = 88.4)

`...`	Ignored. This forces all parameters to be named, which is safer.
`scr.mg.dL`	Numeric. Serum creatinine in mg/dL.
`weight.kg`	Numeric. Body weight in kilograms.
`age.yr`	Numeric. Age in years.
`is.female`	Logical. TRUE for females, FALSE for males.
`scr.umol.L`	Numeric. Alternative specification of serum creatinine in umol/L.
`scr.conversion.factor`	Numeric. A factor for converting serum creatinine from umol/L to mg/dL.

All arguments can be vectors.

A numeric vector containing the estimated creatinine clearance in mL/min.

# With serum creatinine in mg/dL
crcl.cg(scr.mg.dL=0.9, weight.kg=112.9, age.yr=53, is.female=FALSE)

# With serum creatinine in umol/L
crcl.cg(scr.umol.L=0.9*88.4, weight.kg=112.9, age.yr=53, is.female=FALSE)
