data_collection_program: Collect Direct Observation Data

In Observation: Collect and Process Physical Activity Direct Observation Data

Collect Direct Observation Data

Description

A generic-like function for collecting direct observation data manually or interactively, depending on user-specified preference and session capabilities.

Usage

data_collection_program(interactive = TRUE, ...)

Arguments

interactive	Logical. Should program be run interactively?
...	Additional arguments passed to method-like functions (under "See Also" below)

Note

If 'interactive = TRUE', but R is not being used interactively, a message is issued and an override is implemented to set 'interactive = FALSE'.

See Also

example_data

Other collection functions: interactive_data_collection_program(), manual_data_collection_program()

Examples

if (interactive()) {
data_collection_program()
}

# Load Sample of interactively-collected data for comparison
#    with manually-entered data
