This method returns the mutation cause.
Details
Evey mutation is associated to a cause depending on whether it is part of a genomic characterization of a mutant or it is caused by a specific profile. This method returns such a cause whenever it is available.
Examples
# let us build a SNV without specifying any cause for it
snv <- SNV("X", 20002, "T", "A")
# get the cause of `snv` (i.e., "NA")
snv$get_cause()
#> [1] NA
# we can also build a SNV, specifying a cause for it
snv <- SNV("X", 20002, "T", "A", cause = "SBS13")
# get the cause of `snv` (i.e., "SBS13")
snv$get_cause()
#> [1] "SBS13"
