fortify.basis: Convert spline basis instances to 'data.frame'

In ggfortify: Data Visualization Tools for Statistical Analysis Results

Convert spline basis instances to data.frame

Description

Convert spline basis instances to data.frame

Usage

## S3 method for class 'basis'
fortify(model, data, n = 256, ...)

Arguments

model	spline basis object
data	x-values at which to evaluate the splines. Optional. By default, an evenly spaced sequence of 256 values covering the range of the splines will be used.
n	If data is not provided, instead use an evenly-spaced sequence of x-values of this length (plus one, since both endpoints are included). If data is provided, this argument is ignored.
...	other arguments passed to methods

Value

data.frame with 3 columns: Spline (character), x (numeric), and y (numeric); giving the interpolated x and y values for each of the splines in the basis.

Examples

## Not run: 
library(splines)
x <- seq(0, 1, by=0.001)
spl <- bs(x, df=6)
fortify(spl)

## End(Not run)
