In r studio, I'm now working with the dada2 package (Fast and accurate sample inference from amplicon data with single-nucleotide resolution). When I use the derepFastaq function from dada2 to process my data, I get the following error:- Error in FastqStreamer(fl, n = n) : 'Calloc' could not allocate memory (1000000 of 16 bytes) The information below is for the r version of my computer, which has 12 GB of RAM. platform x86_64-w64-mingw32 arch x86_64 os mingw32 system x86_64, mingw32 systems type 64-bit operating system, x64-based processor status major 4 minor 1.0 year 2021 month 05 day 18 svn rev 80317 language R version.string R version 4.1.0 (2021-05-18) nickname Camp Pontanezen memory.limit() = 12193 memory.size() = 80.58 I'm puzzled as to why R won't use all of my RAM.
