One-liner (summary)

GNU R class for vectors of 1-bit booleans

Description

This GNU R package provides bitmapped vectors of booleans (no NAs), coercion from and to logicals, integers and integer subscripts; fast boolean operators and fast summary statistics. With 'bit' vectors you can store true binary booleans {FALSE,TRUE} at the expense of 1 bit only, on a 32 bit architecture this means factor 32 less RAM and ~ factor 32 more speed on boolean operations. Due to overhead of R calls, actual speed gain depends on the size of the vector: expect gains for vectors of size > 10000 elements. Even for one-time boolean operations it can pay-off to convert to bit, the pay-off is obvious, when such components are used more than once.

Reading from and writing to bit is approximately as fast as accessing standard logicals - mostly due to R's time for memory allocation. The package allows one to work with pre-allocated memory for return values by calling .Call() directly: when evaluating the speed of C-access with pre-allocated vector memory, coping from bit to logical requires only 70% of the time for copying from logical to logical; and copying from logical to bit comes at a performance penalty of 150%. the package now contains further classes for representing logical selections: 'bitwhich' for very skewed selections and 'ri' for selecting ranges of values for chunked processing. All three index classes can be used for subsetting 'ff' objects (ff-2.1-0 and higher).

These instructions assume you have setup the repository first (or read it).

To install/use r-cran-bit @ version 1.1-14-1+b1 ...

To install packages, you can quickly setup the repository automatically (recommended):

curl -1sLf \
  'https://dl.cloudsmith.io/public/ultimaker/debian-backup/setup.deb.sh' \
  | sudo -E bash

If you need to force a specific distribution, release/version, architecture, or component (if supported), you can also do that (e.g. if your system is compatible but not identical):

curl -1sLf \
  'https://dl.cloudsmith.io/public/ultimaker/debian-backup/setup.deb.sh' \
  | sudo -E distro=debian codename=buster arch=ARCH component=COMPONENT bash

or ... you can manually configure it yourself before installing packages:

apt-get install -y debian-keyring  # debian only
apt-get install -y debian-archive-keyring  # debian only
apt-get install -y apt-transport-https
# For Debian Stretch, Ubuntu 16.04 and later

sudo chmod 644 ${keyring_location}
sudo chmod 644 /etc/apt/sources.list.d/ultimaker-debian-backup.list
apt-get update
sudo apt-get install r-cran-bit=1.1-14-1+b1
Warning: Note that this package is for Debian 10 (Buster) / armhf and may only work for that configuration.
