Package adeptdata was created to host raw accelerometry data sets and
their derivatives. Some of them are used in the corresponding adept
package.
Install from CRAN.

collected during 25 minutes of an outdoor run. Data were collected at
frequency 100 Hz with two ActiGraph GT9X Link sensors located at left
hip and left ankle. See ?acc_running for details.

collected during outdoor continuous walking from 32 healthy participants
between 23 and 52 years of age. Data were collected at frequency 100 Hz
simultaneously with four wearable accelerometers located at left wrist,
left hip and both ankles. See ?acc_walking_IU for details.

templates derived from accelerometry data collected at four body
locations: left wrist, left hip, left ankle, and right ankle. See
?stride_template for details.
