This means that it tried to allocate 109035k on top of what was already
allocated, and couldn't.

You probably can't fit this model in the memory.  Fortunately you probably
don't want to.

You can almost certainly either aggregate to a smaller number of
observations or analyse subgroups of the data and get a more useful result
as well as one that R can compute.
