# TapeR 0.5.3

- 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

- 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

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

# TapeR 0.5.0

- 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.
