R help - Nov 2019 - Problems with lambda argument

Dear friends,

Hope you are doing great. When setting the lambda = "auto" in the
auto.arima function, I get an error message saying non-numeric argument to
binary operator.

I have performed several tests changing parameters and going through the
other lines of code and as soon as I set lambda = "auto" the error
pops up,
otherwise the model runs perfectly fine.

Any guidance will be greatly appreciated,

Best regards,

Paul

If I run the example(auto.arima) code from the forecast package but add 
lambda="auto", I don't get any error, so I think you'll have
to post a
reproducible example if you want help.

Dear friend Duncan,

Thank you for your kind reply, I appreciate the fact that you always try to
help. I got the error fixed, to fix the problem, instead of setting
lambda="auto", I did lambda=BoxCox.lambda(tsobject), not sure if this
is
equivalent to setting lambda="auto", but I guess is a workaround at
the
very least.

Cheers,

Paul
