[R] R 64-bit memory.limit() is max of ?

[S. Few]

Currently using R 2.92
Win XP


Goal: scale up computing capacity for large datasets (1-5 million records)

I realize under 32 bit versions of R the memory.limit is maxed at 4GB.

Q:
1. What are the limits under 64 bit versions of R? Are those limits OS
dependent?
2. Are there limits to the size of individual objects?”
3. Are there limits or problems in using functions such as lm(),
glm(), rpart(), doBy package, MASS, etc?

Any help is appreciated!
