fm_lattice_Nd: Lattice grids for N dimensions

Description

Construct an N-dimensional lattice grid

Usage

fm_lattice_Nd(x = NULL, ...)
# S3 method for matrix
fm_lattice_Nd(x = NULL, dims = NULL, values = NULL, ...)
# S3 method for data.frame
fm_lattice_Nd(x = NULL, ...)
# S3 method for list
fm_lattice_Nd(x = NULL, dims = NULL, ...)
# S3 method for fm_bbox
fm_lattice_Nd(x = NULL, dims = NULL, ...)
# S3 method for `NULL`
fm_lattice_Nd(x = NULL, ..., dims = NULL)

Value

An fm_lattice_Nd object with elements

dims

integer vector

values

the grid coordinate axis values

loc

matrix of constructed grid coordinates

Arguments

x

list, data.frame, matrix, fm_bbox or NULL. If a list of vectors, as.matrix(expand.grid(x)) is used to create a full grid coordinates. data.frame and matrix input is assumed to follow the same ordering convention as the output of expand.grid(). of length N of vectors or grid matrices of coordinate values. List vector values are sorted before use.

...

Passed on to submethods

dims

numeric; the size of the grid of dimension length(dims)

values

list of grid axis values

Methods (by class)

• fm_lattice_Nd(`NULL`): Ignores the NULL x and creates a lattice based on values (if non-NULL) and dims unit hypercube lattice grid with dims dimensions.
