Error when checking examples (devtools::check() function)

[RamiKrispin]

Hi,

I am getting error from the devtools::check() function while testing the function example:

* checking examples ... ERROR
Running examples in ‘TSstudio-Ex.R’ failed
The error most likely occurred in:

> base::assign(".ptime", proc.time(), pos = "CheckExEnv")
> ### Name: train_model
> ### Title: Train, Test, Evaluate, and Forecast Multiple Time Series
> ###   Forecasting Models
> ### Aliases: train_model
> 
> ### ** Examples

Any idea what causing this error? as I am not able to reproduce this error when running the example in a clean environment.

The full look of the error is available here: https://win-builder.r-project.org/p1ik8pV1o6xF/00check.log

Thanks,

This is what triggered the error on the check:

if(base::all(!is.numeric(level)) ||
     base::any(level %% 1 != 0) ||
     base::any(level  <= 0 || level > 100)){
    stop("Error on the 'level' argument: the argument is out of range (0,100]")
  }

It seems liked that you cannon use the || operator within any function. The following solve this issue:

if(base::all(!is.numeric(level)) ||
     base::any(level %% 1 != 0) ||
     base::any(level  <= 0 | level > 100)){
    stop("Error on the 'level' argument: the argument is out of range (0,100]")
  }

Best,
Rami
