Return whether a cell is in a set location of a matrix

Description

Helper to determine is a cell is in a set location of a matrix or not. Left is useful for, e.g. twin means matrices.

Usage

xmu_cell_is_on(
  r,
  c,
  where = c("diag", "lower", "lower_inc", "upper", "upper_inc", "any", "left"),
  mat = NULL
)

Arguments

r

which row the cell is on.

c

which column the cell is in.

where

the location (any, diag, lower or upper (or _inc) or left).

mat

(optionally) provide matrix to check dimensions against r and c.

Value

  • mxModel()
