  maf,
  geneSet = NULL,
  clinicalData = NULL,
  time = "Time",
  Status = "Status"
)

an MAF object generated by read.maf

geneSet

Examples

laml.maf <- system.file("extdata", "tcga_laml.maf.gz", package = "maftools")
laml.clin <- system.file("extdata", "tcga_laml_annot.tsv", package = "maftools")
laml <- read.maf(maf = laml.maf,  clinicalData = laml.clin)
mafSurvGroup(maf = laml, geneSet = c('DNMT3A', 'FLT3'), time = 'days_to_last_followup', Status = 'Overall_Survival_Status')
