This method builds a data frame representing the CNA.
Details
The data frame contains the columns "chr", "chr_pos",
"length", "alt_base", "allele"", "src_allele", and "type".
Examples
# create an amplification CNA
amp_cna <- Amplification("X", 20002, 100)
amp_cna$get_dataframe()
#> chr chr_pos length allele src_allele type
#> 1 X 20002 100 NA NA A
# create a deletion CNA
del_cna <- Deletion("Y", 40020, 200, 0)
del_cna$get_dataframe()
#> chr chr_pos length allele src_allele type
#> 1 Y 40020 200 0 NA D
