The output of compute_eigen_decomp puts the eigenvalues into a list structure, where each element is a vector that corresponds to the eigenvalues for a given time point. This function does the work of converting the values into a data.frame for more easy analysis.

extract_matrix_values(values_list, id_var = "censusdate")

Arguments

values_list

a list of vectors for the eigenvalues: the number of elements in the list corresponds to the time points of the s-map model, and each element is a vector of the eigenvalues, computed from the matrix of the s-map coefficients at that time step

id_var

when constructing the long-format tibble, what should be the variable name containing the time index

Value

A data.frame with columns for the index variable, the eigenvalue, and the rank
