snv |
A dataframe having sample, chr, pos, ref, alt and/or freq as its columns. The snv dataframe can be created by the |
bsg |
An object of class BSGenome. Default: BSgenome.Hsapiens.UCSC.hg19::Hsapiens |
Estimation of mutation frequency in pre-determined, user-specified nucleotide motif contexts for input samples. The BSgenome object contains the reference genome information, and should be specified for alternative assembly of human genomes or nonhuman reference genomes. The output returns a data frame containing estimated mutation frequencies in the different genomic contexts, as provided in the contextfreq object, for each input sample.
A data frame of class contextfreq containing mutation frequency in user-specified nucleotide contexts.
