Get normalized centroid size

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)
#> $cat
#> [1] 77.4076
#> 
#> $dog
#> [1] 86.78916
#> 
#> $heart
#> [1] 89.2805
#> 
#> $leaf2
#> [1] 74.38899

# Extract from tibble
sizes_norm <- get_centroid_size_norm(bot)

# Add to tibble
bot$cs_norm <- get_centroid_size_norm(bot)
