Plot trajectories and density plots of position by subject

Description

Plots all trajectories and generates density plots of position by subject from elevation and bird's eye views.

Usage

plot_by_subject(obj_name, col_by_treat = FALSE, ...)

Arguments

obj_name

A viewr object (a tibble or data.frame with attribute pathviewr_steps that includes "viewr") that has been passed through separate_trajectories() or get_full_trajectories().

col_by_treat

If multiple treatments or sessions, color data per treatment or session. Treatments must be levels in a column named treatment.

...

Additional arguments passed to/from other pathviewr functions.

Details

The input viewr object should have passed through separate_trajectories() or get_full_trajectories(). Optionally, treatments should have been added as levels in a column named treatment. Two plots will be produced, one from a "bird's eye view" of width against length and one from an "elevation view" of height against length. All trajectories will be plotted on a per subject basis, along with density plots of width or height depending on the view. col_by_treat = TRUE, data will be plotted by color according to treatment in both the trajectory plots and the density plots.

Value

A "bird's eye view" plot and an "elevation view" plot, made via ggplot2.

Examples

library(pathviewr)
library(ggplot2)
library(magrittr)

if (interactive()) {
  ## Import the example Motive data included in the package
  motive_data <-
    read_motive_csv(system.file("extdata",
                                "pathviewr_motive_example_data.csv",
                                package = 'pathviewr'))

  ## Clean, isolate, and label trajectories
  motive_full <-
    motive_data %>%
    clean_viewr(desired_percent = 50,
                max_frame_gap = "autodetect",
                span = 0.95)

  ## Plot all trajectories by subject
  motive_full %>%
    plot_by_subject()

  ## Add treatment information
  motive_full$treatment <- c(rep("latA", 100), rep("latB", 100),
                             rep("latA", 100), rep("latB", 149))

  ## Plot all trajectories by subject, color by treatment
  motive_full %>%
    plot_by_subject(col_by_treat = TRUE)
}
