The following runs me out of memory on OSX with both R3.5 and RStudio 1.1.453. I think it is a mal-formed read of a CSV and then something very bad in the string presentation layer. Only try this if you are willing to run out of memory and force-quit R/RStudio.
# from https://public.tableau.com/s/resources?qt-overview_resources=1
mframe = read.table("https://public.tableau.com/s/sites/default/files/media/IHME_GBD_2010_MORTALITY_AGE_SPECIFIC_BY_COUNTRY_1970_2010.csv",
# quote = '"', # MISTAKE of omission, file uses single quote as apostrophe, need to set quote to just double
header=TRUE, sep=",", stringsAsFactors=FALSE)
dim(mframe)
unique(mframe$Country.Name) # Boom! out of memory
(If you get a partial file download failure, go ahead and retry it. I got this effect on a local copy of the file).
Uncommenting the re-definiton of quote seems to fix it. BTW the data is crap, with "death rates per 100,000" in the 300,000 range.
