It calculates interval AUC of general form. This is useful for pharmacodynamic data.
Usage
gIntAUC(x, y, t1, t2, Outer = "NEAREST")
Value
return interval AUC value (scalar)
Arguments
x
vector values of independent variable, usually time
y
vector values of dependent variable, usually concentration
t1
start time for AUC
t2
end time for AUC
Outer
indicates how to do the out of x range point

Details
This calculates an interval (partial) AUC (from t1 to t2) with the given series of x and y.
If t1 and/or t2 cannot be found within x vector, it interpolates.
If t1 and/or t2 are out of x range, it uses the nearest value.
For concentration data, use IntAUC.
