infix

%||%

R objects, possibly <code>NULL</code>.

X, Y

This is a very simple infix function for the common TractoR idiom whereby
<code>NULL</code> is used as a default argument value, but later needs to be
resolved to a meaningful value if not overridden in the call. It returns its
first argument unless it is <code>NULL</code>, in which case it falls back on the
second argument.

Functions for working with magnetic resonance images. Reading and
writing of popular file formats (DICOM, Analyze, NIfTI-1, NIfTI-2, MGH);
interactive and non-interactive visualisation; flexible image manipulation;
metadata and sparse image handling.
