Older Mac vs Newer Windows - R really can't allocate enough memory?

I'm trying to run a ziplss gamfrom the mgcv package in r. The data.frame is 158,566 obs. of 16 variables.

I'm using my Dell XPS 15. I only got the computer a couple weeks ago and it doesn't have a lot on it. It's a 1 TB SSD with 32 GB of RAM and the 8th gen Core i7 processor.

The model runs for 2 minutes and then says:

Error: cannot allocate vector of size 9.1 Gb

However, the model runs to completion (hours later) on my MacBook Pro, which has a Core i5 processor, 8 GB of RAM, and a 120 GB hard drive, not SSD.

This doesn't make sense, does it?

Do I just need to increase my memory limit on my XPS?

Here's what I have right now:

> memory.limit()
[1] 32505
> memory.size()
[1] 23981.48

If I do need to increase the memory limit: how, and what do I set it to? Especially unsure about what to set it to. I don't want to crash/harm my computer.

Yeah I read that one. I tried stuff like `gc()`, etc. That thread still doesn't tell me what I should increase the memory to. And it also doesn't help me understand why it works on my Mac and not on Apple. Those are the questions I'd like answered. – Heliornis Sep 21 '18 at 03:27

Dose your both Mac and Windows packages same architecture (x64) ? – Mojtaba Tajik Sep 21 '18 at 04:10
Yes, forgot to mention that. Thanks. Both x64. – Heliornis Sep 21 '18 at 04:16
Is your Mac swapping? – Roland Sep 21 '18 at 05:25
@Roland I actually do not know what that means, so I'm not sure. – Heliornis Sep 21 '18 at 13:42
