Standardize the process of bringing various modes of output files into R. Additionally, processes are provided to read and minimally pre- process raw data from primary accelerometer and inertial measurement unit files, as well as binary .gt3x files. ActiGraph monitors are used to estimate physical activity outcomes via body-worn sensors that measure (e.g.) acceleration or rotational velocity.
AGread is for automatically detecting the format of .csv data files from ActiGraph accelerometers, and bringing the data into R. It is designed to streamline and standardize the file-reading process, prior to further processing. Thus, it can be used flexibly to develop new methods for handling ActiGraph data, or to invoke existing methods, many of which exist in other R packages (e.g. PhysicalActivity and TwoRegression), or will soon.
New in AGread 1.2.0, binary .gt3x files can be read in as well.
You can install the development version of AGread from github with:
# install.packages("devtools")devtools::install_github("paulhibbing/AGread")
Or, AGread v0.1.2 is now available on CRAN, and can be installed with:
install.packages("AGread")
In this update, the key new feature is support for reading binary
.gt3x files. Other bugs have been solved related to time variables,
and particularly calculations in epoch lengths other than 1-s. The
major changes are noted below.
