Changes in version 0.2.4                        

  - Added ggplot2 support for plotting: plot.BKP(..., engine = "ggplot")
    now produces ggplot2-based visualizations.
  - Added a package-wide isotropic argument (default: TRUE) to use
    isotropic kernels (a shared length-scale across dimensions); set
    isotropic = FALSE for anisotropic kernels with dimension-specific
    length-scales.

                 Changes in version 0.2.3 (2025-09-22)                  

  - Removed vignettes to avoid redundancy with the arXiv paper and to
    resolve CRAN thread limit issues during vignette building.

                 Changes in version 0.2.0 (2025-09-16)                  

  - Added fitted(), parameter(), and quantile() methods.
  - Updated predict() and simulate() methods: both now return results
    for the training data by default when Xnew is not provided.
  - Extended plot() method with new dims argument for higher-dimensional
    inputs.
  - Added Section 5 to the vignette, presenting a real-data application
    on Loa loa parasite infection in North Cameroon.
  - Added argument checking with informative error messages.

                 Changes in version 0.1.1 (2025-08-19)                  

  - Added a vignette introducing the package.
  - Fixed minor bugs and improved stability.

                 Changes in version 0.1.0 (2025-07-23)
