Melt a polynomial matrix
poly_melt(x)
x |
a matrix created by |
The degree
values are returned as a character vector because they
should be treated categorically (as when plotting). Moreover, matrices
made with multiple vectors (e.g., poly(rnorm(10), rnorm(10), degree = 2)
)
have names that are not numerically meaningful (e.g., 1.0
, 2.0
, 0.1
,
1.1
, 0.2
),
a tibble::tibble()
with three columns: observation
(row number of
the matrix), polynomial degree
, and value
.
m <- poly(rnorm(10), degree = 3) poly_melt(m)
