Using sp::over, RStudio Session abnormally terminated due to an unexpected crash

I am reporting having a problem doing a computation in this project:

Specifically I am getting a message The previous R session was abnormally terminated due to an unexpected crash. You may have lost workspace data as a result of this crash.

This has occurred on multiple occasions and the computation has yet to run to completion on any occasion. It is a computation that takes between 1 and 2 minutes on my own laptop. The output from one instance on my computer is at the end of this post.

In RStudio cloud, it crashes at the following line:

rainfall_interior_spdf <- rainfall_spdf[!, aus_spdf)), ] 

Output when running on my laptop (object sizes of all objects in the environment printed first):

11,488 B
4,420,664 B
17,147,800 B
4,419,176 B

t1 <- Sys.time()
rainfall_interior_spdf <- rainfall_spdf[!, aus_spdf)), ]
t2 <- Sys.time()

t2 - t1
Time difference of 1.335538 mins


Very likely you are exceeding the 1GB RAM memory limit on RStudio Cloud and that hardly would be the case in your local system.

This is my hunch as well.

I am trying to figure out how to debug in this situation. In RStudio Cloud, I get the same error - eventually - upon entering the debug browser to step-through sp::over. (On my own machine, I keep getting an R Session Aborted message instantaneously upon trying to debug sp::over.)
