[R-pkg-devel] Deprecating apparent S3 method, changing name

[Jan van der Laan]

Hmm, the following doesn't seem to trigger warnings or notes in `R CMD 
check --as-cran` (R 4.4.1; linux)

esa <- function(x) { 
  

   UseMethod("esa") 
  

} 
  

  
  

esa.plot <- function(y) { 
  

   .Deprecated("esaPlot") 
  

   esaPlot(y) 
  

} 
  

  
  

esaPlot <- function(y) { 
  

   message("esaPlot") 
  

} 
  

  
  

esa.numeric <- function(x) { 
  

   message("esa.numeric") 
  

} 
  



With NAMESPACE:
  
  

S3method(esa, numeric) 
  

export(esa) 
  

export(esa.plot) 
  

export(esaPlot)

Am I doing something different than you are?
