Generate a sensor structure from a sensor data vector or matrix.

Generate a sensor structure from a sensor data vector or matrix.

sens_struct(
  data,
  sampling_rate = NULL,
  T = NULL,
  depid,
  type,
  unit = NULL,
  frame = NULL,
  name = NULL,
  start_offset = 0,
  start_offset_units = "second"
)

Arguments

data

sensor data vector or matrix
sampling_rate

(optional) sensor data sampling rate in Hz
T

(optional) is the time in seconds of each measurement in data for irregularly sampled data. The time reference (i.e., the 0 time) should be with respect to the start time of the deployment.
depid

string that provides a unique identifier for this tag deployment
type

is a string containing the first few letters of the sensor type, e.g., acc for acceleration. These will be matched to the list of sensor names in the sensor_names.csv file. If more than one sensor matches type, a warning will be given. type can be in upper or lower case.
unit

(optional) units in which data are sampled. Default determined by matching type with defaults in sensor_names.csv
frame

(optional) frame of reference for data axes, for example 'animal' or 'tag'. Default determined by matching type with defaults in sensor_names.csv.
name

(optional) "full name" to assign to the variable. Default determined by matching type to defaults in sensor_names.csv/
start_offset

(optional) offset in start time for this sensor relative to start of tag recording. Defaults to 0.
start_offset_units

(optional) units of start_offset. default is 'second'.

Value

A sensor list with field data containing the data and with metadata fields pre-populated from the sensor_names.csv file. Change these manually as needed (or specify the relevant inputs to sens_struct) to the correct values.

Examples

if (FALSE) {
# example will only work if data matrix Aw is in your workspace.
# A <- sens_struct(data=Aw,sampling_rate=fs,depid='md13_134a', type='acc')
}
