title: R on MacOS Error: vector memory exhausted (limit reached?)
body: <p>I'm trying to run an R script (in particular, I am using the &quot;getLineages&quot; function from the Bioconductor package, <a href="https://www.bioconductor.org/packages/devel/bioc/html/slingshot.html" rel="noreferrer">Slingshot</a>.</p>
  <p>I'm wondering why the error &quot;vector memory exhausted (limit reached?)&quot; is showing up when I use this function, as it doesn't seem to be the most memory-intensive function compared to the other functions in this package (with the data I am analyzing).</p>
  <p>I do understand that there are other questions like this on Stackoverflow, but they all suggest to switch over to the 64-bit version of R. However, I am already using this version. There seem to be no other answers to this issue so far, I was wondering if anyone might know?</p>
  <p>The data is only ~120mb in size, which is far less than my computer's 8GB of RAM.</p>
