Gasfluxes provides functions for fitting non-linear concentration - time models as well as convenience functions for checking data and combining different calculation methods.
The wrapper function for convenient flux calculation is
gasfluxes. Several concentration - time models are implemented
HMR.orig: The original implementation of HMR.
HMR.fit: A new implementation of HMR using partially linear least-squares. This is recommended over HMR.orig.
NDFE.fit: An implementation of the NDFE model using partially linear least-squares.
lin.fit: A simple linear model.
rlin.fit: A simple linear model fit using robust regression.
