Calculating Ratios Between Two Data Sets and Correction for
Adhering Particles on Plants

Calculation of ratios between two data sets containing environmental data like
element concentrations by different methods. Additionally plant element
concentrations can be corrected for adhering particles (soil, airborne dust).

News

ratios 1.2.0

Major changes

Functions are partly renamed to leave the '.' mostly for generic functions

function ratio.ds is now called: ratioDT

function ratio.append_smalles is now called: ratio_append_smallest

function preparation.DT2 is now called: preparationDT2

Bug in correction for adhering particles of method 'M1' removed: Calculation of Errors is optional for functions 'Error = TRUE/FALSE'.

Minor changes

at several occasions better testing for correct dimensions of input data sets

function select.VarsElements has new option 'invert = TRUE/FALSE'.

function ratioDT has new option 'id.vars'. If given, the function is faster.

ratios 1.1.1

Major changes

function ratio.DT1_DT2 is now called: ratio.ds (for "ratio of data sets").
ratio.DT1_DT2 is kept as alias for backwards compatibility

the data set UpperCrust is used as default DT2_replace now only in the function CorrectionAdheringParticles, no longer in the function preparation.DT2

documentation for ratio.ds is improved

ratios 1.1.0

Major changes

function ratio.DT1_DT2: new ratio methods log, ar and cr

function ratio.DT1_DT2: new option 'vars.ref' for the ratio_type 'ar' and 'alr' where the reference element can be provided. If 'vars.ref' is left empty function still asks interactively for the reference element.

Description file contains now the info from the ReadMe

Bug fixes

bug in CorrectionAdheringParticles: checking of the classes of the entries is now working correctly

selectVarsElements finds element duplicates on each object separately and gives a warning

method alr: unnecessary looping replaced by vectored version (much faster now)

function preparation.DT2: if 'vars' are provided and vars are element abbreviations function checks now if all 'vars' are in the data sets and if there are more 'vars' than columns it gives a warning

ratios 1.0.0

Added a NEWS.md file to track changes to the package.
