%description
A user-friendly interactive Shiny interface for the 'BsplineQuantReg'
package, enabling quantile regression using B-splines with shape
constraints, based on the method described in Abbes (2025). Almost all
parameters of the main function 'quantile_spline()' can be tuned. Features
include interactive knot placement, per-region constraint specification,
'CSV' data import, direct demo access, reproducible R code generation, and
solver selection. From version 0.2.2 it handles knots multiplicity,
Bspline basis visualisation, mean-square regression, pp form visualisation
under human readable form, in local or canonical bases, The version 0.2.3
allows regression with spline of any degree, with constraints implemented
for degrees 0 to 5. The GUI provides two modes, basic (compatible with
'BsplineQuantReg' >= 0.2.2) and advanced (requires 'BsplineQuantReg' >=
0.2.6 for stable multiplicity features). This GUI is an R (improved)
version of the 'Python Tk' version of 'BsplineQuantRegPy'.
