TapeS 0.13.0

implemented variance estimates for biomass estimates, based on the NSUR component biomass functions. See details in tprBiomass-helpfile for how this was done.
added function nsur2() implementing the 'simple' biomass functions of Vonderach et al. 2018 (internal).
corrected function nsur(), now using the adjusted tree height (tree height minus stump height) for prediction as detailed in Vonderach & Kändler (2021)
bugfix in internal nsur()-function: one parameter in ash was wrong (led to negative estimates in small trees).
extended tprBiomass: now optionally scale NSUR- to NFI-estimate
moved internal data to sysdata instead of data/, hence, package runs also if not attached (e.g. calls via TapeS::tprVolume don't break)
added citation file
corrected minor bugs, some internal improvements

function tprVolume now with MSE and interval information
function tprDiameter now returns estimated MSE for the mean and prediction when interval='MSE'
added 'sHt' into tprObject
added function FormTariff() to fix taper form according to German NFI observations instead of giving a second measured diameter
added 'inv'-parameter into tprTrees-constructor
corrected component biomass function, now total mass includes needle mass
improved plotting function
improved documentation

updated the relative taper models for beech, oak and red oak, adding a lower diameter to the relative data based on BDAT to stabilise taper curves.

added new TapeR-models for beech, oak and red oak based on pre-smoothed data used during BDAT model building. These models now are the default models for these species; the original TapeR-models based one sectional data are now pushed to species code 37, 38 and 39, respectively. Updated all functions to handle the extended data set.
corrected bug in function HDxoR()
technical adjustments

added height tariff based on German NFI data to estimated tree height given diameter in breast height (DBH)

corrected bug in bdat_as_tprtrees(), when passing more than one tree from rBDAT::buildTree (class 'datBDAT')
added 37th tree species based on an additional taper curve model, which is build on pre-smoothed beech data used during development of BDAT.
corrected bug in plot function
added function and indicator for residual variance to be set to zero to force taper curve through measurements; even more options possible
added support diameter D001 (in 1% of height) at the stem base to avoid non-monotoneous taper curves for such trees (mainly very small trees of certain species). The support diameter is added based on the population average relation between D001 and D05.

allow for small diameter increase in taper curve when checking monotonicity (increase <= 1% of diameter)
constraint in bark function: never return negative double bark thickness (c.f. e.g. Japanese larch) and diameter after bark deduction might not be smaller than zero

corrected bug in tprDiameter, when bark=FALSE and interval != 'none'
corrected biomass estimation: tprBiomass now return aboveground biomass without component needles as the underlying functions do not include needles.

re-implemented component biomass estimation to get rid of dplyr/tidyr-dependency. Now component biomass is estimated using newly developed NSUR-biomass functions. Implemented using Rcpp.
added coercion function to coerce nfi, sectional and bdat data

removed dependency on (unpublished) rBDATPRO-package, implementing biomass function via RCpp (instead call to rDBATPRO)
added monotonicity check of taper curve right into class-constructor

included fitted TapeR models (data: SKPar) and updated corresponding data help file. Added this News file.
