Calculate the normalized centroid size (centroid size divided by perimeter).
Usage
get_centroid_size_norm(x, ..., .cols = NULL)
centsize_norm(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 scalar
If x is a list: returns a numeric vector
If x is a tibble: returns a numeric vector extracted from coo column
Details
For tibbles, this function extracts values without modifying the tibble.
Use within mutate() to add as a column: mutate(df, cs_norm = get_centroid_size_norm(coo))
Examples
get_centroid_size_norm(shapes$cat)
#> [1] 77.4076
get_centroid_size_norm(shapes)
#> [1] 77.40760 86.78916 89.28050 74.38899
# Extract from tibble
sizes_norm <- get_centroid_size_norm(bot)
# Add to tibble
bot$cs_norm <- get_centroid_size_norm(bot)
