center_out_grid: Create multidimensional grid of values

In omkarakatta/ivqr: Instrumental Variables Quantile Regression

Create multidimensional grid of values

Description

Apply center_out_uni element-wise to each argument of this function and take all possible combinations of coordinate grid values to create a data frame of grid coordinates

Usage

center_out_grid(center, increment, length)

Arguments

center	Output of get_initial_beta_D; values that act as the center of each axis of the grid (numeric vector of length p_D)
increment	Granularity of the grid in each axis (numeric vector/list of length p_D)
length	Number of grid values to the right and left of each axis (numeric vector/list of length p_D)

Details

If the grid axis corresponding to one of the beta_D's should be be assymetric, let increment and/or length be a list instead of a vector where the corresponding element is itself a vector of length two.

Value

A data frame with each row acting as the coordinates of the grid. If center is a named vector, the columns of the data frame will share the names of the vector. If center is not a named vector, the columns of the data frame are Var1, Var2, etc.
