Extracts subsets of frames from a Frames object

Source: R/auxiliary.R

An input Frames object is subject to subsetting. This function is useful e.g. when the trajectory of interest is presenting gaps (i.e. does not actually include a frame)

select.Frames(frames, framesToKeep = 1, ...)

Arguments

frames

A Frames object

framesToKeep

A vector containing the indexes of the frames to keep in the selection

...

Arguments to be passed to methods

Value

A Frames object, composed by the subset of frames of the input Frames
