Interpol: Interpolate y value

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

Description

It interpolates y value when a corresponding x value (xnew) does not exist within x vector

Usage

1
Interpol(x, y, xnew, Slope, b0, down = "Linear")

Arguments

x

vector values of x-axis, usually time

y

vector values of y-axis, usually concentration

xnew

new x point to be interpolated, usually new time point

Slope

slope of regression log(y) ~ x

b0

y value of just left point of xnew

down

either of "Linear" or "Log" to indicate the way to interpolate

Details

This function interpolate y value, if xnew is not in x vector. If xnew is in x vector, it just returns the given x and y vector. This function usually is called by IntAUC function Returned vector is sorted in the order of increasing x values.

Value

new x and y vector containing xnew and ynew point
