envalysis is an R package containing miscellaneous functions for data analyses in environmental chemistry and ecotoxicology. Provides, for example, calibration()
to calculate calibration curves and corresponding limits of detection (LODs) and quantification (LOQs) according to German DIN 32645:2008-11. texture()
makes it easy to estimate soil particle size distributions from hydrometer measurements (ASTM D422-63(2007)e2). Some functions of the package require ggplot2 or drc.
Currently, the following functions are available:
CI()
and standard errors se()
rmse()
lod()
and limit of quantification (LOQ) loq()
