Functions for Processing Accelerometer Data

accelerometry's Issues

counting number of bouts

Hello mister Van Domelen

My name is Gabriela Cárdenas and I am working with accelerometer data from an european project.
I am using your package accelerometry (congratulations on this great work¡).
I used your package to create a variable indicating if the 1 minute epoch is part of a bout of at least 10 minutes.
I calculated the accumulated minutes spent in bouts of at least 10 minutes.
Now I want to calculate the number of bouts per day of at least 10 minutes, but I can not find the way or package to do so. Do you think I can use your package for this? Do you know how?

Thank you very much

Possible error in vignette - bouts

In the vignette code example for bouts,

mvpa <- bouts(counts = counts.21007,
bout_length = 10,
thresh_lower = 2020,
tol = 2,
tol_lower = 100)
sum(mvpa)
#> [1] 10075
With this more forgiving algorithm, the subject is considered to have 21 rather than 0 minutes of bouted MVPA over the course of the week.

the function seems to classify nearly all data as MVPA bout, although it seems that it should be 21 minutes given the following sentence. Is this an error in the bouts function?
