Generate summary data frame for inner polygon — x3p_insidepoly

This function generates a summary data frame for the inner polygon of an x3p object.

Usage

x3p_insidepoly_df(
  x3p,
  mask_col = "#FF0000",
  concavity = 1.5,
  b = 10,
  ifplot = FALSE
)

Arguments

x3p: An x3p object representing a topographic scan.
mask_col: A string representing the color to be used for the polygon.
concavity: A strictly positive number used in concaveman::concaveman to influence the shape of the polygon.
b: A positive integer representing the block size for x3ptools::x3p_average.
ifplot: A Boolean flag indicating whether to save ggplot lists in the output attributes.

Value

A data frame summarizing the inner polygon. The data frame includes the following columns:

x: The x coordinates from the x3p object.
y: The y coordinates from the x3p object.
value: The height values from the x3p object.
mask: The mask values from the x3p object.
n_neighbor_val_miss: The number of immediate neighbors, including the point itself, that are missing.
sd_not_miss: The standard deviation of the immediate neighbors that are not missing.

Examples

x3p <- x3p_subsamples[[1]]

insidepoly_df <- x3p_insidepoly_df(x3p, mask_col = "#FF0000", concavity = 1.5, b = 1, ifplot = TRUE)
