TapeR 0.5.3 (2023-08-16)

• in case of non-availability of apVar, stop Taper_FIT_LME.f() with appropriate error message, i.e. the value hold by element 'apVar' of the fitted lme-object

TapeR 0.5.2 (2023-02-25)

• improved calculation of approximate confidence intervals for diamter estimation in E_DHx_HmDm_HT.f() in case of sHT > 0. Especially changed smooth.spline estimation of confidence bands from fixed degrees of freedom to all.knots=TRUE to more precisely follow the data, especially at the lower stem part. Also updated the return list to reflect the approximate MSE in all elements, not only in the confidence bounds (before, list elements hold the information of expected taper curve, without the extra uncertainty due to measurement error in tree height).

TapeR 0.5.1 (2023-02-10)

• added KOV_Mean and KOV_Pred to output of E_DHx_HmDm_HT.f()

TapeR 0.5.0 (2022-01-11)

• minor adjustments for submission to CRAN

TapeR 0.4.3

• added function resVar() for more flexibility in residual error assumptions, hence, changed and renamed the R0 interface: now called Rfn awaiting a list instead of logical

TapeR 0.4.2

• included 'R0'-interpolation to E_HDx_* and Hx_root.f
• improved root-finding in E_Hdx_* so that error is avoided when taper curve is not monotonically decreasing, which might happen rarely in rather abnormal taper forms. The maximum height of searched diameter is returned.

TapeR 0.4.1

• improved the XZ_BSPLINE.f()-function to make it faster. This especially means that it does not return both X and Z matrices but only X or Z as they are only dependent on order and knots.
