reparametrize() method for streamline objects

Source: R/parametrize.R
reparametrize-fiber-streamline-method.Rd

Resamples a single streamline onto a uniform arc-length grid. See reparametrize() for the full parameter documentation.

Arguments

x

A streamline object.

n_points

Number of equally-spaced arc-length points to use.

  • For a single streamline, defaults to nrow(x@points).

  • For a bundle, defaults to the rounded mean number of points across all streamlines.

Pass NULL to use these defaults explicitly.

Value

A streamline reparametrized onto the new grid. The returned object has the same class as the input but with @points resampled to exactly n_points rows and all @point_data vectors resampled correspondingly via linear interpolation.

Examples

pts <- matrix(runif(30), ncol = 3)
colnames(pts) <- c("X", "Y", "Z")
sl <- streamline(points = pts, point_data = list(FA = runif(10)))
sl_reparam <- reparametrize(sl, n_points = 20)
sl_reparam@n_points  # 20
#> [1] 20
