##### Arguments

- obs
- A vector (numeric or factor) of the outcome data

- For bootstrapping, this is either a matrix (for numeric outcomes) or a data frame (for factors). For cross-validation, a vector is produced.
- index
- The list to index of samples in each cross--validation fold (only used for cross-validation).
- keepData
- A logical for returning the observed and predicted data.

##### Details

The mean and standard deviation of the values produced by `postResample`

are calculated.

##### Value

- A list with:
metrics A vector of values describing the bootstrap distribution. data A data frame or `NULL`

. Columns include`obs`

,`pred`

and`group`
