gam package changes

[topepo]

You are receiving this message because you are the maintainer of one
of the following packages which depend on package 'gam': agridat,
arsenal, Ball, bandit, BiodiversityR, biomod2, broom, caret,
CausalGAM, DiceEval, dissever, drtmle, earth, ElemStatLearn, fscaret,
GAMens, LinRegInteractive, locfit, LSC, MapGAM, medflex, mtsdi,
oddsratio, prediction, ProDenICA, RPPanalyzer, scalpel, slp, sm, ssym,
subsemble, SuperLearner, tmle.npvi, tsModel, xpose4, yaImpute .
Because of conflict with gam in mgcv, the S3 class name for a gam
object in gam_1.15 is now 'Gam'. Consequently all the S3 method names
have changed as well, such as plot.Gam. This may or may not affect
your package. This is an annoyance, not least to me, but became a
requirement. Please respond to this email ONLY if you have an error to
report in gam. Thank you, Trevor Hastie

There doesn't appear to be any (known) timeline for this nor is there an implementation to test against.

If you have installed from github and find that these changes have caused an error, I will test and send this to CRAN as soon as I know that gam has been updated.
