Usage

thin(x, jump_size = NULL, n = NULL, neg = FALSE)

Arguments

x	the vector to be thinned
jump_size	pick every 'jump_size'th element
n	pick (roughly) length elements, ie set 'jumps = length(x) / n.'
neg	Return the elements picked (default behaviour) or the complement (ie all the other elements).

Details

If you've got 200 frames for a video and want to thin it to around 40, then use this.

Examples

thin(1:19, jump = 5)
thin(1:20, n = 6)
