Hi all I have searched for a solution to the following problem and even tried emailing the original poster, but have not had any luck in finding an answer.

The function runs to completion, and doesn't seem to be affected by the warnings. However, I am also weary as to why R is warning me about reaching my total memory allocation without throwing up an error and stopping the function, which has always happened in the past... Garbage collection is not a solution here as disused objects are cleared from memory before the evaluation within the function occurs at which the memory limit is likely being hit. Can anyone please offer an explanation as to why a warning would be reached but not an error? Even if the memory ceiling is hit during an internal evaluation or object assignment that the rest of the function does not "require" to run to completion, wouldn't an error still be called?
