Name orthogonal polynomial coefficients

Add standard names to an opoly coefficient vector.

Usage

opoly_name(x)

Arguments

x

Numeric vector of opoly coefficients (length = degree + 1).

Value

Named numeric vector with names in the format x0, x1, x2, ..., xN where x0 is the intercept.

Details

Names are assigned as x0 (intercept), x1, x2, ..., xN where N is the polynomial degree.

Examples

# Create unnamed coefficient vector
coefs <- runif(6)  # degree 5
opoly_name(coefs)
#>        x0        x1        x2        x3        x4        x5
