The `resample`

function uses a kernel function to resample a target
array. This can be thought of as a generalisation of array indexing which
allows fractional indices. It is (S3) generic. The `rescale`

function
is an alternative interface for the common case where the image is being
scaled to a new size.

`x` |
Any object. For the default method, this must be coercible to an array. |

`points` |
Either a matrix giving the points to sample at, one per row, or a list giving the locations on each axis, which will be made into a grid. |

`kernel` |
A kernel function object, used to provide coefficients for each resampled value, or the name of one. |

`...` |
Additional options, such as kernel parameters. |

`pointType` |
A string giving the type of the point specification being
used. Usually can be left as |

`factor` |
A vector of scale factors, which will be recycled to the
dimensionality of |

If a generalised sampling scheme is used (i.e. with `points`

a
matrix), the result is a vector of sampled values. For a grid scheme (i.e.
with `points`

a list, including for `rescale`

), it is a
resampled array.
