Dear R Developers, In the same way that MySQL/MariaDB's Engine InnoDB or MyISAM/Aria have the innodb_buffer_pool_size or the key_buffer_size for setting the maximum amount of RAM which can be used by a Server Instance: ?Would it be possible to create an R Configuration Variable which fixes the maximum amount of RAM memory to be used as Commit / Dynamic Memory Allocation? Thank you. Juan

...' has wrappers for posix setrlimit [1] e.g. unix::rlimit_as() limits address space. This works pretty well, however I found that the way memory is managed and counted varies a lot per OS and malloc implementation. You can also set rlimits on a single evaluation via the rlimit parameter in sys::eval_safe(). [1] http://pubs.opengroup.org/onlinepubs/009695399/functions/getrlimit.html
