title: package ‘vegan’ was installed by an R version with different internals
body: <p>I have installed R-3.4.4 for Windows (32/64 bit) and RStudio 1.1.442 - Windows Vista/7/8/10. I installed package of vegan 2.4-6. When I try opening it then I get the message:</p>
  
  <pre><code>&gt; install.packages("C:/Users/Na Talia/Rpackages/vegan_2.4-6.zip", repos = NULL, type = "win.binary")
  
  Installing package into ‘C:/Users/Na Talia/Documents/R/win-library/3.4’
  
  (as ‘lib’ is unspecified)
  
  package ‘vegan’ successfully unpacked and MD5 sums checked
  
  &gt; library("vegan", lib.loc="~/R/win-library/3.4")
  
  Error: package ‘vegan’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version
  
  In addition: Warning message:
  package ‘vegan’ was built under R version 3.5.0 
  </code></pre>
  
  <p>Any help? Thank you for your time in advance. </p>
  
  <p>P.S. I get the same message in R as well. I reinstalled vegan several times but nothing helps.</p>
