Description Usage Arguments Author(s) Examples

Function to swap landmark sequences within an individual or across an entire array

1	LMK_swap(a, l1, l2)

`a`	a p x k x n matrix of landmark coordinates
`l1`	a numeric vector of landmark index (sequence number) to be changed
`l2`	a numeric vector of landmark index (Sequence number) to change to

lmks <- cbind(1:10, 1:10, 1:10)
plot(lmks, col = rainbow(10), pch = 16) ## plot sequence (in 2 dimensions)
lmks2 <- LMK_swap(lmks, l1 = c(2,8), l2 = c(8,2)) ## flip landmarks 2,8
plot(lmks2, col = rainbow(10), pch = 16) ## show flipped landmarks
