title: how to use na_rm with rpy2 rlf.tapply function
body: <p>I'm using rpy2 to run a piece of R code in Python and trying to use the tapply functionality from R as follows:</p>
  
  <pre><code>import rpy2.rlike.functional as rlf
  import rpy2.robjects.packages as rpackages
  minT = rlf.tapply(all_data['T'], list(date), min, na_rm=True)
  </code></pre>
  
  <p>However, I get this error:
  TypeError: tapply() got an unexpected keyword argument 'na_rm'</p>
  
  <p>In the R code it is na.rm, and I know I need to switch "." to "_" in rpy2. How do I solve this error? Thanks!</p>
