survival analysis in R

Question

[jyotsnap]

how to derive overall survival from geo dataset in R studio, please mention code and packages to install also

[jyotsnap]

Thankyou for providing link...will you please help me in coding of dataset GSE 29272(Gastric cancer) ...i have to get overall analysis report of this particular dataset survival analysis in R

[jyotsnap]

library(survival)
  library(RegParallel)

  res <- RegParallel(
    data = coxdata,
    formula = 'Surv(Time.RFS, Distant.RFS) ~ [*]',
    FUN = function(formula, data)
      coxph(formula = formula,
        data = data,
        ties = 'breslow',
        singular.ok = TRUE),
    FUNtype = 'coxph',
    variables = colnames(coxdata)[9:ncol(coxdata)],
    blocksize = 2000,
    cores = 2,
    nestedParallel = FALSE,
    conflevel = 95)
  res <- res[!is.na(res$P),]
  res

please explain this part of code (survival analysis in R) for getting hazard ratio...what is formula, data and breslow, please clarify

Sure, you want a beer with that, too?
