lm Regression takes 24+ GB RAM - Error message
...with the calculated columns as the
variables
The RAM consumption goes rapidly up and stays at 24 GB for a couple of
minutes.
The result:
Error: cannot allocate vector size of 5.0 Mb
In addition: There ware 50 or more warnings (use warnings() to see the first
50)
--> Reached total allocation of 24559Mb
My code works perfectly fine for a smaller dataset. I am surprised about the
errors as the CPU should do all the work with the lm calculations and the
output cannot be that large, can it??? (I cannot check the object size of
the lm object due to the error)
Right now I am running only 1 linear mod...
