Possible issue in stats/arima.R package
...mod' variable assignment at line 190:
mod <- makeARIMA(trarma[[1]], trarma[[2]], Delta, kappa, SSinit)
I am trying to confirm whether this is intended behavior or possibly an
overlooked detail. Could someone please clarify if the current logic is
correct?
Thank you.
Best regards,
Norbert Kuder

stats/ar.R issue - else branch never used
...min(xaic) else
ifelse(xaic == maic, 0,
Inf), 0L:order.max)
Because maic is always 0 or 1, is.finite(maic) is always T, so the else
branch (ifelse(xaic == maic, 0, Inf)) never executes.
Please check if my finding is valid.

stats/HoltWinters.R inverted logic in seasonal in R and C
...as.double(max(min(gamma, 1), 0)),
as.integer(start.time),
as.integer(seasonalChoice),
as.integer(f),
as.integer(!is.logical(beta) || beta),
as.integer(!is.logical(gamma) || gamma),
...
)
}
Please check the proposed solution.
