Internal function to convert a distantia data frame into a matrix.

Usage

utils_distantia_df_to_matrix(df = NULL, x = "x", y = "y", value = "psi")

Arguments

df

(required, data frame) data frame typically resulting from distantia(), but others are accepted as long as the columns x, y, and value are available. Default: NULL

x

(required, character string) Name of the column with the names of the matrix columns. Default: "x"

y

(required, character string) Name of the column with the names of the matrix rows. Default: "y"

value

(required, character string) Name of the column with values.

Value

dist matrix
