Error running Radme code

[MislavSag]

I have just installed the package and tried smaple code from GitHub Readme:

library(finnts)

# prepare historical data
hist_data <- timetk::m4_monthly %>%
  dplyr::rename(Date = date) %>%
  dplyr::mutate(id = as.character(id))

# call main finnts modeling function
finn_outp33ut <- forecast_time_series(
  input_data = hist_data,
  combo_variables = c("id"),
  target_variable = "value",
  date_type = "month",
  forecast_horizon = 3,
  back_test_scenarios = 6, 
  models_to_run = c("arima", "ets"), 
  run_global_models = FALSE, 
  run_model_parallel = FALSE
)

I get an error

Hey Mislav Sagovac (@MislavSag) can you please let me know what version of R you are using?

[MislavSag]

I am on latest version, 4.3.3. I have updateded all packages including fnints, but still getting an error:

Hmm this is a strange error, since this is the same code that runs as tests every day in CRAN. So in theory it should work. I would suggest checking if the finnts dependencies are old on your machine, and update them if needed. Also maybe try using another data set. For example the quarterly data set from timetk instead.
