The standard deviation of all patch areas at class level(vector data)

This function allows you to calculate the standard deviation of all patch areas belonging to one class in a categorical landscape in vector data format

vm_c_area_sd(landscape, class_col)

Arguments

landscape

the input landscape image,

class_col

the name of the class column of the input landscape

Value

the returned calculated standard deviation of areas of each class is in column "value", and this function returns also some important information such as level, class number and metric name.

Examples

vm_c_area_sd(vector_landscape, "class")
#> # A tibble: 3 × 5
#>   level class id    metric  value
#>   <chr> <chr> <chr> <chr>   <dbl>
#> 1 class 1     NA    area_sd    NA
#> 2 class 2     NA    area_sd    NA
#> 3 class 3     NA    area_sd    NA
