Description

Calculate connectivity metrics

Usage

calc_metrics(lines, lakes, map = FALSE)

Arguments

lines	sf lines object
lakes	sf polygon object
map	logical show a map output of the results?

Details

Examples

## Not run: 

data(nhd_sub_lines)
data(nhd_sub_lakes)
coords <- c(lon = -73.17581, lat = 41.38634)

calc_metrics(nhd_sub_lines, nhd_sub_lakes)

# don't error if lines is only one row
calc_metrics(nhd_sub_lines[1,], nhd_sub_lakes)
