Builds an Ldk object

In Momocs, Ldk classes objects are lists of configurations of landmarks, with optionnal components, on which generic methods such as plotting methods (e.g. stack) and specific methods (e.g. fgProcrustes). Ldk objects are primarily Coo objects. In a sense, morphometrics methods on Ldk objects preserves (x, y) coordinates and LdkCoe are also Ldk objects.

Usage

Ldk(coo, fac = dplyr::tibble(), links = NULL, slidings = NULL)

Arguments

coo: a list of matrices of (x; y) coordinates, or an array, or an Ldk object or a data.frame (and friends)
fac: (optionnal) a data.frame of factors and/or numerics specifying the grouping structure
links: (optionnal) a 2-columns matrix of 'links' between landmarks, mainly for plotting
slidings: (optionnal) a 3-columns matrix defining (if any) sliding landmarks

Value

an Ldk object

Details

All the shapes in x must have the same number of landmarks. If you are trying to make an Ldk object from an Out or an Opn object, try coo_sample beforehand to homogeneize the number of coordinates among shapes. Please note that Ldk methods are as experimental.

implementation of $slidings is inspired by geomorph
