title: Problem loading large .RData file: Error reading from connection
body: <p>I have an .RData file that is rather large. It takes up 1.10 GB on my hard drive, it contains a data frame with 100 variables and 12 million observations. Now when I try to load it, I can open the task manager and watch  the memory usage go all the way up to 7450 MB; at which point my RAM is completely exhausted, and I get &quot;Error reading from connection.&quot; I'm pretty sure this memory deficiency is the problem, but how can that be? Like I said, the .RData is only 1.10 GB.</p>
  <p>I'm using R x64 4.0.5. If it's any clue, when I open the 32-Bit version of R (4.0.5) it tells me &quot;Error: memory exhausted (limit reached?)&quot;, reinforcing my suspicion that this is a memory issue.</p>
  <p>I am unable to access the data any other way, I have to make the .RData file work or it's gone. Why does R require more than 8 GB of RAM to load a 1GB workspace?</p>
