samp_annot.RdSample annotations can be used to store information about
each sample such as tumor type or treatment status. These are used in
downstream plotting functions such as plot_exposures or
plot_umap to group or color samples by a particular annotation.

samp_annot(object, name) <- valueA musica object generated by
the create_musica function or a musica_result
object generated by a mutational discovery or prediction tool.
The name of the new annotation to add.
A vector containing the new sample annotations. Needs to be the same length as the number of samples in the object.
A new object with the sample annotations added to the table in the
sample_annotations slot.
See sample_names to get a vector of sample names in
the musica or musica_result object.
