computeTPRS: Create TPRS basis

In jpkeller/spconf: Computing Scales of Spatial Smoothing for Confounding Adjustment

Create TPRS basis

Description

Compute TPRS basis for given spatial coordinates

Usage

computeTPRS(coords, maxdf, rearrange = TRUE, intercept = FALSE)

Arguments

coords	Data frame containing the coordinates.
maxdf	Largest number of splines to include in TPRS basis
rearrange	Logical indicator of whether to rearrange the columns of TPRS basis
intercept	Logical indicator of whether or not to remove the intercept column

Details

This function creates a TPRS basis using the mgcv package from the given coordinates with the option to rearrange the columns such that last two columns are moved to the left of the matrix and the third-from last column, which corresponds to the intercept, is optionally removed.

x <- runif(100)
y <- runif(100)
mat <- computeTPRS(data.frame(x, y), maxdf=4)
