If your numbers are not integers then they are double
precision which means 8 bytes per number. In such a
case you will need 86000*2500*8 = 1.7Gb of memory
(plus a small amount for book keeping). You will need
more (and sometimes much more) if you intend to do
some operations on your arrays). So yo
If this is numeric, then for just storing one copy, you will require
86000 * 2500 * 8 = 1.7GB of memory. You should have 3-4X that if you
want to analyze it, so you might need about 6GB of physical memory and
a 64-bit version of R. Is there some other alternative? Do you need
all the values at o
Hi All,
is there a way of predicting memory usage?
I need to build an array of 86000 by 2500 numbers (or I might create
a list of 2 by 2500 arrays 43000 long). How much memory should I
expect to use/need?
Cheers,
Fede
