This function reads one or more NIfTI-1, NIfTI-2 or ANALYZE-7.5 files into
R, using the standard NIfTI C library.
Usage
readNifti(file, internal = FALSE, volumes = NULL)
Value
An array or internal image, with class "niftiImage" (and
possibly also "internalImage"), or a list of such objects if
file has length greater than one.
Arguments
file
A character vector of file names.
internal
Logical value. If FALSE (the default), an array
of class "niftiImage", containing the image pixel or voxel values,
will be returned. If TRUE, the return value will be an object of
class "internalImage", which contains only minimal metadata about
the image. Either way, the return value has an attribute which points to a
C data structure containing the full image.
volumes
An integer vector giving the volumes to read (counting along
all dimensions beyond the third jointly), or NULL, the default, in
which case every volume is read. This cannot currently be set differently
for each file read.
