The mean value of all core areas in landscape(vector data)

This function allows you to calculate the mean value of all core patch areas in a categorical landscape in vector data format

vm_l_core_mn(landscape, edge_depth)

Arguments

landscape

the input landscape image,

edge_depth

the fixed distance to the edge of the patch

Value

the returned calculated mean value of core area of the whole landscape is in column "value", and this function returns also some important information such as level and metric name, Moreover, class number and the "id" column, although both are "NA" here in the landscape level

Examples

vm_l_core_mn(vector_landscape, edge_depth= 1)
#> # A tibble: 1 × 5
#>   level     class id    metric    value
#>   <chr>     <chr> <chr> <chr>     <dbl>
#> 1 landscape NA    NA    core_mn 0.00882
