Examples

## See the 'mut_matrix()' example for how we obtained the following
## mutation matrix.
mut_mat_s <- readRDS(system.file("states/mut_mat_s_data.rds",
                                    package="MutationalPatterns"))

## Extracting signatures can be computationally intensive, so
## we use pre-computed data generated with the following command:
# nmf_res_strand <- extract_signatures(mut_mat_s, rank = 2)

nmf_res_strand <- readRDS(system.file("states/nmf_res_strand_data.rds",
                                        package="MutationalPatterns"))

## Provide column names for the plot.
colnames(nmf_res_strand$signatures) = c("Signature A", "Signature B")

plot_signature_strand_bias(nmf_res_strand$signatures)
