title: Limit Command in R?
body: <p>What is the take a limit command or function in R? </p>
  
  <p>(I could not find it by searching using ? and ?? functions or in introductory manuals. lim() and limit() do not exist.)</p>
  
  <p>This is in the sense of limit X->Y+ of F(X). I don't mean anyone writing code; I mean, included in R as installed standard, what the supplied function is called. </p>
  
  <p>(Note: my previous question on this topic has been edited to be fully clear ... but it is still on hold... I suppose that moderators forgot about it ... hence this question.)</p>
