Get coordinate ranges

Calculate the range (min, max) for each coordinate axis.

Usage

get_range(x, ..., .cols = NULL)

Arguments

x

A matrix (nx2), list of matrices, or tibble with coo columns.

...

Additional arguments (reserved for future use).

.cols

Column name(s) to process when x is a tibble. If NULL, automatically detects columns containing coo objects.

Value

• If x is a single matrix: returns a 2x2 matrix (rows: min/max, cols: x/y)

• If x is a list: returns a list of 2x2 matrices

• If x is a tibble: returns a list of 2x2 matrices extracted from coo column

Details

Returns a matrix where row 1 is min values and row 2 is max values for x and y. This is not a scalar, so cannot be used with measure().
