R help - Feb 2020 - Error: cannot allocate vector of size 6.5 Gb

Dear R-Help members;

I have the following error messages when I would like to create
training and testing data for Random Forest.

Your help is highly appreciated.

Regards,
Greg

inTrain <- createDataPartition(a, p = 0.7, list = FALSE)
Error: cannot allocate vector of size 6.5 Gb

What help do you want, exactly?  The error message seems pretty clear. 
Your data set "a" is such that trying to apply the function results in
asking for more memory than can be allocated.

Without knowing something about "a" it is impossible to say more. 
Members of this list do not, as far as I know, have psychic powers.

cheers,

Are you running the 32-bit or 64-bit version of R?  The 32-bit version
cannot allocate that much space; on Windows, the maximum contiguous space
that can ever be allocated in a 32-bit process is a little over 1Gbyte, on
Unix it's larger but cannot go over the 32-bit address space limit of
4Gbytes.

Cheers,
