### Description

Compute summary statistics (min, max, mean, and quartiles) for SpatRaster using base `summary` method. A sample is used for very large files.

For single or other statistics see `Summary-methods`, `global`, and `quantile`

### Usage

    ## S4 method for signature 'SpatRaster'
    summary(object, size=100000, warn=TRUE, ...)

    ## S4 method for signature 'SpatVector'
    summary(object, ...)

### Arguments

`object` | SpatRaster or SpatVector
`size` | positive integer. Size of a regular sample used for large datasets (see `spatSample`)
`warn` | logical. If `TRUE` a warning is given if a sample is used
`...` | additional arguments passed on to the base `summary method`

### Value

matrix with (an estimate of) the median, minimum and maximum values, the first and third quartiles, and the number of cells with `NA` values

### Examples

    set.seed(0)
    r <- rast(nrows=10, ncols=10, nlyrs=3)
    values(r) <- runif(nlyr(r)*ncell(r))
