onebasis_inla: Create a One-Dimensional Basis for INLA

Description

This function is a wrapper around onebasis to create a one-dimensional basis for spline modeling. This wrapper enhances the original function by allowing users to specify a custom prefix for the column names using the basis_name argument, such that each set of basis variables can be easily identified in the model formula by the INLA framework.

Usage

onebasis_inla(covariate, fun, basis_name, ...)

Value

An object of class "onebasis", as returned by onebasis, with column names modified according to basis_name.

Arguments

covariate

A numeric vector representing the covariate

fun

A character string specifying the shape function to be used by onebasis.

basis_name

A character string giving a base name for the columns in the resulting basis matrix. The default prefix (usually "b") is replaced by this string.

...

Additional arguments passed to onebasis, such as degree, df, knots, etc.

Examples

# Import example data set
data("dengue_MS")

# Build a one-dimensional spline basis with a custom name
ob_inla <- onebasis_inla(
 covariate = dengue_MS$tmin,
 fun = "bs",
 basis_name = "tempBasis",
 degree = 2
)

# Check class of the one-basis object
class(ob_inla)

# View first rows of the one-basis matrix
head(ob_inla)
