Knitting to xaringan slides - pandoc errors

[mwauben]

I am having trouble knitting a .Rmd file to HTML. Yesterday it was perfectly happy. Today I re-cloned from Github, opened the file, and pressed 'Knit' to get the HTML slides, but it failed with the following pandoc errors:

label: setup (with options) 
List of 1
 $ include: logi FALSE

  |..............................                                        |  43%
  ordinary text without R code

  |........................................                              |  57%

You are running out of RAM memory (RStudio Cloud is currently limited to 1GB), try cleaning your environment before knitting to release already allocated memory.

I suppose the CSV I was loading to show was too big to keep in memory. Will have a play with cleaning it mid-knit. Thank you!
