Convert data from another format into a viewr object

Source: R/data_import_functions.R
as_viewr.Rd

Should you have data from a non-Motive, non-Flydra source, this function can be used to ensure your data are put into the right format to work with other pathviewr functions.

Usage

as_viewr(
  obj_name,
  frame_rate = 100,
  frame_col,
  time_col,
  subject_col,
  position_length_col,
  position_width_col,
  position_height_col,
  include_rotation = FALSE,
  rotation_real_col,
  rotation_length_col,
  rotation_width_col,
  rotation_height_col
)

Arguments

obj_name

A tibble or data frame containing movement trajectories

frame_rate

Must be a single numeric value indicating capture frame rate in frames per second.

frame_col

Column number of obj_name that contains frame numbers

time_col

Column number of obj_name that contains time (must be in seconds)

subject_col

Column number of obj_name that contains subject name(s)

position_length_col

Column number of obj_name that contains length-axis position values

position_width_col

Column number of obj_name that contains width-axis position values

position_height_col

Column number of obj_name that contains height-axis position values

include_rotation

Are rotation data included? Defaults to FALSE

rotation_real_col

Column number of obj_name that contains the "real" axis of quaternion rotation data

rotation_length_col

Column number of obj_name that contains the length axis of quaternion rotation data

rotation_width_col

Column number of obj_name that contains the width axis of quaternion rotation data

rotation_height_col

Column number of obj_name that contains the height axis of quaternion rotation data

Value

A tibble that is organized to be compliant with other pathviewr functions and that contains the attributes pathviewr_steps with entries set to c("viewr", "renamed_tunnel", "gathered_tunnel")

Examples


## Create a dummy data frame with simulated (nonsense) data
df <- data.frame(frame = seq(1, 100, by = 1),
                 time_sec = seq(0, by = 0.01, length.out = 100),
                 subject = "birdie_sanders",
                 z = rnorm(100),
                 x = rnorm(100),
                 y = rnorm(100))

## Use as_viewr() to convert it into a viewr object
test <-
  as_viewr(
    df,
    frame_rate = 100,
    frame_col = 1,
    time_col = 2,
    subject_col = 3,
    position_length_col = 5,
    position_width_col = 6,
    position_height_col = 4
  )
