bases (version 0.2.0)

bases_mgcv: mgcv integration

Description

Provides methods so that bases expansions can be used as user-defined smooth classes in mgcv::s(). The k argument to s() maps to the main dimension parameter of each basis. Other arguments should be passed via the xt argument to s(), and will be forwarded to the basis function.

Examples

if (requireNamespace("mgcv", quietly = TRUE)) {
    x = 1:150
    z = c(1:50, rep(1, 100))
    y = as.numeric(BJsales)
    m = mgcv::gam(y ~ s(x, bs = "b_bart", k=10) + s(z, bs = "b_bart", k=20))
    summary(m)
    plot(x, y)
    lines(x, fitted(m), type="s", col="blue")
}
