flux package

• Very wide ranging: "Several functions for the estimation of greenhouse gas (GHG) flux rates using closed chamber concentration measurements. The package follows a modular concept: Fluxes can be calculated in just two simple steps or in several steps if more control is wanted. Functions for further analyses (GPP and Reco model fitting and prediction for budgets including error terms) are also available."
• Handles all three major GHGs and calibration
• Fit quality checks, plotting routines (base R)

gasfluxes package

• "This vignette introduces the gasfluxes package to calculate soil greenhouse gas fluxes from static chamber measurements. The package offers different models for measured concentration-time relationships from static chambers within the function gasfluxes: linear, robust linear, HMR, original HMR, NDFE
• Interesting, also helps you select between results: "The most extensively tested decision ruleset is kappa.max, which optimises the balance between bias and uncertainty by taking the minimal detectable flux of the current system"
• Has a nice vignette and paper

HMR package

• "HMR reads static chamber data from a semicolon/comma separated ASCII text file and analyzes the selected data series by either user selected (with decision support) models or by user configured automatically selected models. Results are exported to a semicolon/comma separated ASCII text file."

FluxCalR package

• "This R package is used to calculate CO2 and CH4 gas fluxes measured with static chamber method. It provide an easy way to calculate multiple flux measurements from one data file."
• On GitHub, not CRAN
• CO2 and CH4
• Interactive selection of timepoints on graphs
• Has LoadLGR function for loading raw LGR data

That was useful. Now I am ready to talk with @wilsonsj100 tomorrow :)
