Reduce the time span of a dataset — crop

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.

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).

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.

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.

Examples

d <- find_dives(beaked_whale$P,300) 
         X <- crop_all(c(d$start[1], d$end[1]), beaked_whale)  #crop all data to 1st dive
         plott(X = list(X$P, X$A), r = c(1, 0), panel_labels = c('Depth', 'Acc')) 
         # plot shows the dive profile and acceleration of the first dive
