plot_gof: Plot goodness-of-fit
In kgori/sigfit: Flexible Bayesian inference of mutational signatures

plot_gof plots the goodness-of-fit of a set of samples, each of which has typically been sampled using an signature extraction model with a different number of signatures.

1	plot_gof(sample_list, stat = "cosine")

`sample_list`	List containing the results of signature extraction using `extract_signatures` with multiple numbers of signatures (see argument `nsignatures` in `extract_signatures`).
`stat`	Function for measuring goodness-of-fit. Admits character values `"cosine"` (cosine similarity, default) or `"L2"` (L2 norm or Euclidean distance).
