estdim: Estimate Raster Dimensions

In kuwisdelu/matter: Out-of-core statistical computing and signal processing

Estimate Raster Dimensions

Description

Estimate the raster dimensions of a scattered 2D signal based on its pixel coordinates.

Usage

estdim(x, tol = 1e-6)

Arguments

x	A numeric matrix or data frame where each column gives the pixel coordinates for a different dimension. Only 2 or 3 dimensions are supported if the coordinates are irregular. Otherwise, any number of dimensions are supported.
tol	The tolerance allowed when estimating the resolution (i.e., pixel sizes) using estres(). If estimating the resolution this way fails, then it is estimated from the coordinate ranges instead.

Value

A numeric vector giving the estimated raster dimensions.

Examples

co <- expand.grid(x=1:12, y=1:9)
co$x <- jitter(co$x)
co$y <- jitter(co$y)

estdim(co)
