how to make a code break if max memory is reached

In RStudio, there are some occasions when the max memory is reached for some of my codes, e.g. 

Warning messages:
1: In dlData$unique_id <- paste(dlData$institution_key,  ... :
  Reached total allocation of 16322Mb: see help(memory.size)
2: In dlData$unique_id <- paste(dlData$institution_key,  ... :
  Reached total allocation of 16322Mb: see help(memory.size)
3: In `$<-.data.frame`(`*tmp*`, "unique_id", value = c("100003|19920822",  ... :
  Reached total allocation of 16322Mb: see help(memory.size)
4: In `$<-.data.frame`(`*tmp*`, "unique_id", value = c("100003|19920822",  ... :
  Reached total allocation of 16322Mb: see help(memory.size)

Usually, in such case, the code still continues to run to the next step, but I am not sure if my code really ran fine. Is it possible to break the code if the max memory is reached, i.e any settings in R?

You could make your code stop on any warning message by setting

options(warn=2)

If your code is otherwise clean enough (i.e., you never get any other warnings), then this should work fine. I don't know offhand of a way to catch just one specific warning.
