cpr’s progress argument has been
extended to control if a progress bar is used for just the cpr steps, or
if a more detailed progress for of the influence weight calculations is
reported.
influence_of_iknots gains parallel execution via
pbapply (#17)
plot.cpr_cp gains the argument
comparitive which, when set to FALSE and only
one cpr_cp is passed in for plotting, the graphic will
appear more like the plot.cpr_bs results. When
comparitive = TRUE or more than one cpr_cp is
present, the behavior from v0.3.0 is retained.
cp.formula gains the methods.args
argument to pass arguments to the regression method instead of relying
on ....
d_order_statistic and p_order_statistic
were added. These functions allow you to get the density of distribution
function for the jth order statistic from a sample of size n from a
distribution with defined density and distribution functions within
R.
sign_changes will count the number of sign changes
of the first or second derivative of a spline function.
get_spline returns standard errors and derivatives

loglikelihood is not exported in the namespacesummary.cpr_cp now calculates the “wiggle” of the
function by default, that is, changes the default from
wiggle = FALSE to wiggle = TRUEcp and cn both have the default
keep_fit argument set to TRUE. This change was made to
simplify the prediction methods.print.cpr_bt returns the object invisibly, it used to
return a str(x).print.cpr_cn returns the object invisiblyprint.cpr_cnr returns the object invisiblyprint.cpr_cpr returns the object invisiblyRefactor of c++ defining basis functions, derivatives of basis functions, b-splines structures
cp.formula checks the formula and
requires that bsplines is used once and is the first term
on the right hand side of the formula.

influence_of and plot.cpr_influence_of
provide a clean interface for users to explore the influence of a set of
knots on a spline function. (#19)color (TRUE/FALSE) option
added to plot.cpr_bs.plot.cpr_cn lets the user plot 2D surfaces for tensor
product surfaces. The plots are for the whole surface if the input is a
2D tensor product, and is a 2D slice evaluated at a given value for
other margins for 3+ dimensional tensor products.is. a collection of is.cpr_cp,
is.cpr_bs, … functions added.spdg has been added to the package.build_tensor definitionThis version has a fairly polished set of tools for b-splines, cpr, and cnr. This version seems to be in a good place for use in the three major papers
Continued development should be focused on bug fixes and minor enhancements.

the control polygon. When plotting multiple control polygons and
splines, this option will make it easier to view the spline
functions.First version of univariable cpr methods ready for deployment
cpr::cp and cpr::cpr have been used for the
simulations which are aimed to be part of the first manuscript.
Modifications might be needed, but hopefully the univariable methods are
stable.
A lot of changes in the implementation and API have occurred from the
0.0.x series. The aim for version 0.2.0 will be to have a very similar
API for cpr::cn and cpr::cnr as provided for
the cpr::cp and cpr::cpr calls.
bsplineDbsplinesgenerate_cp_datadeboor.cpp file so that the
bsplines are accessible. The prior design only allowed
access to the basis, the current design allows access to the generic
B-splines.Version 0.0.3 is the version of the package used to run the analysis and simulations presented in the paper submitted to the 28th International Biometrics Conference, Western North American Region (WNAR) of the Internal Biometric Society, Student paper competition. The conference will be held 10 - 16 July 2016 in Victoria, British Columbia, Canada.

Version 0.0.1.9003 was the first stable version for fitting the exact data model.
This version was based on the idea that using an angle to reduce the control polygon was a good idea. Further literature review and simulations showed otherwise. This version is marked for posterity and the cpp functions are going to be useful in the following versions as well.
