summary function

summary

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 methods

## 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

Returns

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