sp2d | R Documentation |

2-dimentional radial spline generator used in `cpglmm`

```
sp2d(x1, x2, k = max(20, min(length(x1)/4, 150)), by = NULL,
allPen = FALSE, varying = NULL, diag = FALSE,
knots1 = quantile(x1, probs = 1:k/(k + 1)),
knots2 = quantile(x1, probs = 1:k/(k + 1)))
```

`x1` |
the first covariate in the coordinate |

`x2` |
the second covariate in the coordinate |

`k` |
number of knots |

`by` |
not used. This is just for compatibility with |

`allPen` |
not used. This is just for compatibility with |

`varying` |
not used. This is just for compatibility with |

`diag` |
not used. This is just for compatibility with |

`knots1` |
vector of knot locations for the first covariate in the coordinate |

`knots2` |
vector of knot locations for the second covariate in the coordinate |
