Hi everyone,
I am trying to perform a multiple imputation with mice on a dataset of about
13000 observations and 178 variables. I can start an "empty" imputation
("imp_start <- mice(data, maxit=0)"), but after a few minutes R stops with the
following error message:
Error: cannot allocate vector of size 2.0 Gb
In addition: Warning messages:
1: In col(value) :
Reached total allocation of 8078Mb: see help(memory.size)
2: In col(value) :
Reached total allocation of 8078Mb: see help(memory.size)
3: In unique.default(x) :
Reached total allocation of 8078Mb: see help(memory.size)
4: In unique.default(x) :
Reached total allocation of 8078Mb: see help(memory.size)
5: In unique.default(x) :
Reached total allocation of 8078Mb: see help(memory.size)
6: In unique.default(x) :
Reached total allocation of 8078Mb: see help(memory.size)
I am using R (with R Studio) on Windows 7, my computer has a total of 8 GB RAM.
Following advice I found on the internet, I installed the newest R-version
(64-bit) and tried the following commands:
memory.size(max = F)
memory.limit(size=NA)
But I still get the same error. Now I am wondering, if my dataset is really to
large for mice or R? Or is there any other setting I could use to increase
memory size for R? I would really appreciate if anyone who is familiar with
this problem would share their insights...
Thanks,
Jen
