interpol {qpNCA}

Interpolate Concentrations

Description

Interpolates concentrations. Used by correct.xx functions to interpolate concentrations. Uses linear interpolation unless method is 2 (log down), c1 > c2, and both concentrations are non-zero.

Usage

interpol(c1 = NA, c2 = NA, t1 = NA, t2 = NA, t3 = NA, method = 1)

Arguments

c1

concentration 1 lagconc

c2

concentration 2 leadconc

t1

time 1 tiem where conc should be calculated

t2

time 2 lagtime

t3

time 3 leadtime

method

calculation method (1, 2, or 3)
