resample_to: Resample an image with readable method names

Description

A convenience front-end to [resample()] that accepts human-friendly method names and an engine switch. Internally delegates to the S4 `resample(source, target, interpolation = 0/1/3)` methods.

Usage

resample_to(
  source,
  target,
  method = c("nearest", "linear", "cubic"),
  engine = c("internal"),
  ...
)

Value

A `NeuroVol` in the target space

Arguments

source

A `NeuroVol` (source image)

target

A `NeuroVol` or `NeuroSpace` to match

method

Interpolation method: `"nearest"`, `"linear"`, or `"cubic"`

engine

Resampling engine. For now only `"internal"` is supported.

Examples

# \donttest{
img <- read_vol(system.file("extdata","global_mask_v4.nii", package="neuroim2"))
sp  <- space(img)
sp2 <- NeuroSpace(sp@dim*2, sp@spacing/2, origin=sp@origin, trans=trans(img))
r1  <- resample_to(img, sp2, method = "linear")
# }
