bind_viewr_objects: Bind viewr objects

In pathviewr: Wrangle, Analyze, and Visualize Animal Movement Data

Bind viewr objects

Description

Combine a list of multiple viewr objects into a single viewr object

Usage

bind_viewr_objects(obj_list)

Arguments

obj_list

A list of viewr objects

Value

A single viewr object (tibble or data.frame with attribute pathviewr_steps that includes "viewr") that combines all the rows of the source viewr objects in obj_list. Metadata may not necessarily be retained and therefore attributes should be used with caution.

Examples

## Since we only have one example file of each type provided
## in pathviewr, we will simply import the same example multiple
## times to simulate batch importing. Replace the contents of
## the following list with your own list of files to be imported.

## Make a list of the same example file 3x
import_list <-
  c(rep(
    system.file("extdata", "pathviewr_motive_example_data.csv",
                package = 'pathviewr'),
    3
  ))

## Batch import
motive_batch_imports <-
  import_batch(import_list,
               import_method = "motive",
               import_messaging = TRUE)

## Batch cleaning of these imported files
## via clean_viewr_batch()
motive_batch_cleaned <-
  clean_viewr_batch(
    file_announce = TRUE,
    motive_batch_imports,
    desired_percent = 50,
    max_frame_gap = "autodetect",
    span = 0.95
  )

## Alternatively, use import_and_clean_batch() to
## combine import with cleaning on a batch of files
motive_batch_import_and_clean <-
  import_and_clean_batch(
    import_list,
    import_method = "motive",
    import_messaging = TRUE,
    motive_batch_imports,
    desired_percent = 50,
    max_frame_gap = "autodetect",
    span = 0.95
  )

## Each of these lists of objects can be bound into
## one viewr object (i.e. one tibble) via
## bind_viewr_objects()
motive_bound_one <-
  bind_viewr_objects(motive_batch_cleaned)

motive_bound_two <-
  bind_viewr_objects(motive_batch_import_and_clean)

## Either route results in the same object ultimately:
identical(motive_bound_one, motive_bound_two)
