If you want everything appended to the end of the R G NIR arrays, you
can do something like this, for the 2nd files and later:

r = [[r], [data[1,*]]]
g = [[g], [data[0,*]]]
nir = [[nir], [data[2,*]]]

Otherwise, you can declare r g nir as arrays of pointer (size = k), each
of them pointing to your data... you can easily fill them up in a loop,
when reading your files.
