title: roxygen2: Issue with exporting print method
body: <p>I have updated to roxygen2 v4.0.0 and am now attempting to convert @S3method and @method commands to @export commands following the directions <a href="https://stackoverflow.com/questions/7198758/roxygen2-how-to-properly-document-s3-methods/22598266#22598266">here</a>.  This seems to have worked well for all of my methods except for those related to print.</p>
  
  <p>Here is a toy example that illustrates my problem (I understand the silliness of the example).  Here is the .R file ...</p>
  
  <pre><code>#' Test.
  #' 
  #' Test.
  #'@aliases zzzTest print.zzzTest summary.zzzTest
  #'@param v A numeric vector.
  #'@param x A \code{zzzTest} object.
  #'@param object A \code{zzzTest} object.
  #'@param \dots Additional arguments for the S3 methods.
  #'@return A \code{zzzTest} object.
  #'@keywords manip
  #'@examples
  #'z &lt;- zzzTest(runif(10,1,2))
  #'print(z)
  #'summary(z)
  #'@rdname zzzTest
  #'@export zzzTest
  zzzTest &lt;- function(v) {
    tmp &lt;- log(v)
    class(tmp) &lt;- "zzzTest"
  }
  
  #'@rdname zzzTest
  #'@export
  print.zzzTest &lt;- function(x,...) { print(x, ...) }
  
  #'@rdname zzzTest
  #'@export
  summary.zzzTest &lt;- function(object,...) { summary(object) }
  </code></pre>
  
  <p>And this is the .Rd file that results from roxygenising ...</p>
  
  <pre><code>% Generated by roxygen2 (4.0.0): do not edit by hand
  \name{zzzTest}
  \alias{print.zzzTest}
  \alias{summary.zzzTest}
  \alias{zzzTest}
  \title{Test.}
  \usage{
  zzzTest(v)
  
  print.zzzTest(x, ...)
  
  \method{summary}{zzzTest}(object, ...)
  }
  \arguments{
  \item{v}{A numeric vector.}
  
  \item{x}{A \code{zzzTest} object.}
  
  \item{object}{A \code{zzzTest} object.}
  
  \item{\dots}{Additional arguments for the S3 methods.}
  }
  \value{
  A \code{zzzTest} object.
  }
  \description{
  Test.
  }
  \examples{
  z &lt;- zzzTest(runif(10,1,2))
  print(z)
  summary(z)
  }
  \keyword{manip}
  </code></pre>
  
  <p>My use of @export seems to work fine for the summary method (note the \method()), but not for the print method (note no \method() and only print.zzzTest).  I was also successful using @export for several other methods in other .R files.  My problems only seem to occur with the print method.</p>
  
  <p>Can someone point out where I am going wrong?  Thank you in advance for any help with this problem.</p>
  
  <p>For what it is worth, I am using R 3.1.0, RStudio 0.98.501, and roxygen2 4.0.0.</p>
  
  <p><strong>UPDATE 1:</strong> There is an export(print.zzzTemp) but not an S3method(print,zzzTemp) in the namespace ... i.e., the same problem as ZNK (in the comments).</p>
  
  <p><strong>UPDATE 2:</strong> I copied the exact .R file into another package, roxygenized that package, and the .Rd file (and corresponding namespace) were created properly.  This implies that I have some "switch" related to roxygen2 different between the two packages, but I can't seem to isolate the difference or find such a "switch" (I believe that I have only controlled roxygen through the project options in RStudio).</p>
