Interpolate between two point in a coordinates object.

Usage

interpolate_ternary(x, length_out = 200)

Arguments

x: Row of a coordinates file. Should contain columns `x_1`, `y_1`, `z_1`, `x_2`, `y_2`, `z_2`, for example in the output of `merge_coords()`.
length_out: Total length of output `data.frame`.

Value

`data.frame` with interpolated points added. All other variables are copied to fill.

Examples

row <- data.frame(x_1 = 0, y_1 = 0, z_1 = 0,
                  x_2 = 1, y_2 = 1, z_2 = 1)
interpolate_ternary(row, length_out = 5)
