Miscellaneous Functions for Environmental Analyses
envalysis is an R package containing miscellaneous functions for data
analysis in environmental chemistry and ecotoxicology. Provides, for example,
calibration() to calculate calibration curves and corresponding limits of
detection (LODs) and limits of quantification (LOQs) according to German DIN
texture() makes it easy to estimate soil particle size
distributions from hydrometer measurements (ASTM D422-63, 2007).
Some functions of the package require ggplot2 or drc.
Currently, the following functions are available:
lod()and limits of quantification
loq()as part of the
calibrationclass to produce linear calibration curves in accordance with German DIN 32645 (2008)
texture(); see vignette for details
CI(), standard errors
se(), and root mean square errors
