Same result here with the same error message mentioned in my first post. I tried it in Texmaker which is my usual Latex editor, not that I do much in Latex, and then tried it in RStudio and it is still choking.
Interestingly EMACS will process it and produce a pdf but it simply produces. It also provides this warning: : Latex Warning; Reference 'fig:plot-figheight' undefined on page 2 on input line 14. It seems to repeat the same message for each of the other figures.
