gbm 2.1.5 2019-01-14

  • Fixed bug that occurred whenever distribution was a list (e.g., “pairwise” regression) (#27).

  • Fixed a bug that occurred when making predictions on new data with different factor levels (#28).

  • Fixed a bug that caused relative.influence() to give different values whenever n.trees was/wasn’t given for multinomial distributions (#31).

  • The plot.it argument of gbm.perf() is no longer ignored (#34).

  • Fixed an error that occurred in gbm.perf() whenever oobag.curve = FALSE and overlay = FALSE.

gbm 2.1.4 2018-09-14

  • Switched from CHANGES to NEWS file.

  • Updated links and maintainer field in DESCRIPTION file.

  • Fixed bug caused by factors with unused levels (#5).

  • Fixed bug with axis labels in the plot() method for "gbm" objects (#17).

  • The plot() method for "gbm" objects is now more consistent and always returns a "trellis" object (#19). Consequently, setting graphical parameters via par will no longer have an effect on the output from plot.gbm.

  • The plot() method for "gbm" objects gained five new arguments: level.plot, contour, number, overlap, and col.regions; see ?plot.gbm for details.

  • The default color palette for false color level plots in plot.gbm() has changed to the Matplotlib ‘viridis’ color map.

  • Fixed a number of references and URLs.
