Tvol: Total Volumen of Activity for Whole Dataset
In junruidi/actigraphy: Feature Extraction from Minute Level Actigraphy Data

Description Usage Arguments Details Value Examples

Calculate total volume of activity level, which includes TLAC (total log transfored activity counts), TAC (total activity counts).

1	Tvol(count.data, weartime, logtransform = FALSE)

`count.data`	`data.frame` of dimension n*1442 containing the 1440 minute activity data for all n subject days. The first two columns have to be ID and Day.
`weartime`	`data.frame` with dimension of `count.data`. The first two columns have to be ID and Day.
`logtransform`	if `TRUE`, then calcualte `TLAC`. Or calculate `TAC`.

log transormation is defined as log(x+1).

A dataframe with some of the following columns

`ID`	identifier of the person
`Day`	indicator of which day of activity it is, can be a numeric vector of sequence 1,2,... or a string of date
`TAC`	total activity count
`TLAC`	total log activity count

data(example_activity_data)
count = example_activity_data$count
wear = example_activity_data$wear
tac = Tvol(count.data = count,weartime = wear,logtransform = FALSE)
