Points to Poly

Here we introduce the function points_to_poly.

This function intends to take a dataframe of points and convert them into polygons. This can be done either by creating a circular plane around each point given a set diameter, through Alpha Hull, or via MCP.

It requires a few argumeasd:

  points2Poly <- function(points,x = 'x', y = 'y', species = 'species', map,
                        alpha = FALSE, a = 1,
                        type = 'All', buffer_m = 1000){...}

• points

  a 3 column dataframe of points, where the columns are species, x, and y

• x

  the column containing the x coords

• points

  • a 3 column dataframe of points, where the columns are species, x, and y

• x

  • the column containing the x coords

• y

  • the column containing the y coords

• species

  • the column containing the species

• map

  • the boundary map for the species (can omit, but reccomended to use map_create function or provide your own)

• alpha

  • boolean to determine if you want to create alpha hull (will change to a vector of options)

• a

  • the alpha parameter to use

• type

  • need to change

• buffe_m

  • the buffer radius in meters
