R Documentation

Reduce the time span of a dataset

Description

This function is used to reduce the time span of a dataset by cropping out any data that falls before and after two time cues.

Usage

crop_all(tcues, X)

Arguments

`tcues`	A two-element vector containing the start and end time cue in seconds of the data segment to keep, i.e., tcues = c(start_time, end_time).
`X`	A sensor list or a set of sensor lists (e.g., from load_nc).

Details

Possible input combinations: crop_all(X) if X is a sensor list or set of sensor lists, crop_all(tcues, X, Y, ...) if X, Y, ... are sensor lists.

Value

A sensor list or set of sensor lists containing the cropped data segment. The output data have the same units, frame and sampling characteristics as the input. The list may have many sublists which are additional sensor structures as required to match the input.

Examples

d <- find_dives(beaked_whale$P,300) 
         X <- crop_all(c(d$start[1], d$end[1]), beaked_whale)	#crop all data to 1st dive
         plott_base(X = list(X$P, X$A), r = c(1, 0), panel_labels = c('Depth', 'Acc'))
