shrink.gbm() and
shrink.gbm.pred(); the latter seemed broken anyway. Happy
to accept a PR if anyone wants to fix them.Non-file package-anchored link(s) in documentation...
warning.Corrected the number of arguments for
gbm_shrink_gradient() in gbm-init.c (#50).
(Thanks to CRAN for highlighting the issue.)
Removed unnecessary dependency on gridExtra.
Switched to using lapply() instead of
parallel::parLapply() whenever
n.cores = 1.
Calling gbm() with
distribution = "bernoulli" will now throw an error whenever
the response is non-numeric (e.g., 0/1 factors will throw an error
instead of possibly crashing the session.) (#6). (Thanks
to @mzoll.)
Calling gbm() with
distribution = "multinomial" now comes with a warning
message; multinomial support has always been problematic and since this
package is only being maintained for backwards compatibility, it likely
will not be fixed unless someone makes a PR.
Switched from RUnit to tinytest
framework. The test.gbm(),
test.relative.influence(), and validate.gbm()
functions will remain for backwards compatability. This is just the
start, as more tests will be added in the future (#51).
Fixed a long standing bug that could occur when using k-fold cross-validation with a response that’s been transformed in the model formula (#30).
Fixed a but that would crash the session when giving “bad” input
for n.trees in the call to predict.gbm() (#45).
(Thanks to @ngreifer.)
Fixed a bug where calling predict() could throw an
error in some cases when n.trees was not
specified.
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.
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.
