Retrieve exposures from a musica_result object

Source: R/methods.R

The exposure matrix contains estimated amount of each signature for each sample. Rows correspond to each signature and columns correspond to each sample.

exposures(result)

# S4 method for musica_result
exposures(result)

exposures(result) <- value

# S4 method for musica_result,matrix
exposures(result) <- value

Arguments

result

A musica_result object generated by a mutational discovery or prediction tool.
value

A matrix of samples by signature exposures

Value

A matrix of exposures
