             Summary: Handle R method breaking signature changes
                 Key: SPARK-22281
                 URL: https://issues.apache.org/jira/browse/SPARK-22281

this WARNING on R-devel

* checking for code/documentation mismatches ... WARNING
Codoc mismatches from documentation object 'attach':
attach
  Code: function(what, pos = 2L, name = deparse(substitute(what),
                 backtick = FALSE), warn.conflicts = TRUE)
  Docs: function(what, pos = 2L, name = deparse(substitute(what)),
                 warn.conflicts = TRUE)
  Mismatches in argument default values:
    Name: 'name' Code: deparse(substitute(what), backtick = FALSE) Docs: deparse(substitute(what))

Checked the latest release R 3.4.1 and the signature change wasn't there. This likely indicated an upcoming change in the next R release that could insur this new warning when we attempt to publish the package.

Not sure what we can do now since we work with multiple versions of R and they will have different signatures then.
