envalysis: Miscellaneous Functions for Environmental Analyses

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.

Minor improvements

• First CRAN release
• Better package description
• loq() now uses iterations instead of estimating the value from lod()

Bug fixes

• Better handling of unbalanced designs in calibration()
• Reimplementation of drc's mselect() for texture() to get rid of global variables

Defunct functions

• make.raw(), use rep() instead
