Calculate the span (max - min) for each coordinate axis.
Usage
get_range_diff(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 numeric vector of length 2 (x_span, y_span)
If x is a list: returns a list of numeric vectors
If x is a tibble: returns a list of numeric vectors extracted from coo column
Details
Returns the absolute distance spanned along each axis.
This is not a scalar (it's a 2-element vector), so cannot be used with measure().
