This function evaluates the splines basis functions. Unlike the
bSpline in the splines2 package, this function
returns the value of a single spline basis, rather than a vector of
values for all the spline basis functions.
splinesBasis(x, knots, degree, intercept = TRUE, i,
boundary.knots = c(0, 1))vector, the values at which to evaluate the basis function.
vector, the internal knots.
integer, the degree of the splines.
boolean, default set to TRUE. This includes
an additional component to the basis splines so that the
splines are a partition of unity (i.e. the sum of all
components equal to 1).
integer, the basis component to be evaluated.
vector, default is c(0, 1).
scalar.
