Convert vectorized data back to volume

Description

Un-applies a mask to vectorized data to yield its volumetric representation. The mask and data should have compatible dimensions: the number of rows in dat should equal the number of locations within the mask.

Usage

unvec_vol(dat, mask, fill = NA)

Arguments

dat

Data matrix with locations along the rows and measurements along the columns. If only one set of measurements were made, this may be a vector.

mask

Volumetric binary mask. TRUE indicates voxels inside the mask.

fill

The value for locations outside the mask. Default: NA.

Value

The 3D or 4D unflattened volume array
