manual_tree_intensity {Observation} | R Documentation |
Manually implement the pre-classification decision tree described at the end of Supplemental Document 3 from Hibbing et al. (2018, *Med Sci Sports Exerc*).
manual_tree_intensity(prompt_responses)
prompt_responses |
A vector of responses to the decision tree prompts |
The vector of responses must match the structure indicated in the example, i.e., a named vector answering prompts in the following order: participant seated; large muscles contracting; slow contractions; contractions slowed by resistance; activity is ambulatory; ambulation is slow enough to be considered light activity rather than moderate or vigorous.
prompt_responses <- structure(c("yes", "no", NA, NA, NA, NA),
.Dim = c(6L, 1L), .Dimnames = list(c("seated",
"large_muscles_moving", "slow", "slowed_by_resistance",
"ambulation", "light_walking"),
"1"))
