title: How to use objects from global environment in Rstudio Markdown
body: <p>I've seen similar questions on Stack Overflow but virtually no conclusive answers, and certainly no answer that worked for me.</p>
  
  <p>What is the easiest way to access and use objects (regression fits, data frames, other objects) that are located in the global R environment in the Markdown (Rstudio) script.</p>
  
  <p>I find it surprising that there is no easy solution to this, given the tendency of the RStudio team to make things comfortable and effective.</p>
  
  <p>Thanks in advance.</p>
