vctors package returning error: Can't subset columns past the end.

[RickPack]

I cannot provide the dataset that caused this error the first time so using the economics dataset from the ggplot2 package:

Error in `df[, i]`:
! Can't subset columns past the end.
ℹ Location 1 doesn't exist.
ℹ There are only 0 columns.

> packageVersion('forester')
[1] ‘1.1.4’
> packageVersion('vctrs')
[1] ‘0.5.2’

Reproducible example

library(forester) library(ggplot2)

test_model <- train( economics %>% select(-date), type = 'regression', y = 'uempmed', engine = c('ranger', 'xgboost', 'decision_tree', 'lightgbm'))

---

✔ Type guessed as: regression

-------------------- CHECK DATA REPORT --------------------

The dataset has 574 observations and 5 columns, which names are: pce; pop; psavert; uempmed; unemploy;

With the target value described by a column uempmed.

✔ No static columns.

✔ No duplicate columns.

✔ No target values are missing.

✔ No predictor values are missing.

✔ No issues with dimensionality.

✖ Strongly correlated, by Spearman rank, pairs of numerical values are:

pce - pop: 0.99; pce - psavert: -0.79; pop - psavert: -0.84;

✖ These obserwation migth be outliers due to their numerical columns values: 514 515 516 517 518 520 521 522 523 524 525 527 528 529 530 531 ;

✖ Target data is not evenly distributed with quantile bins: 0.24 0.45 0.06 0.26

✔ Columns names suggest that none of them are IDs.

✔ Columns data suggest that none of them are IDs.

Try converting the dataset to as.data.frame(economics) before passing it to the train function. I think the function does not accept tibble type.

@jmanacup , thank you, that solved the "location 1 doesn't exist" error. Now I see an XGBoost error. label must be provided when data is a matrix

I will open another issue.
