[R-pkg-devel] Forward function call

  I think quote(survival::coxph) will work in place of as.name() ?

Hello,

the function 'coxreg' in my package 'eha' is often just a wrapper for
'coxph' in survival, so I have code like

      if (cox.ph){
          Call <- match.call()
          Call[[1]] <- as.name("coxph")
          fit <- eval.parent(Call)
          return(fit)
      }

which works since eha depends on survival. Now I am thinking of changing
Depends to Imports, and I would like to change the code to

      if (cox.ph){
          Call <- match.call()
          Call[[1]] <- as.name("survival::coxph")
          fit <- eval.parent(Call)
          return(fit)
      }

but this doesn't work, because the function name is turned into
`survival::coxph` (with the backticks) and the evaluation fails.

How can I solve this?

Thanks, G,
