4D data acsess
Hi, I have a 4D data file from MATLAB, call it X, that I want to analyze in
R. The first 3 dimensions are x y z coordinates and the forth is a value in
time.
If you took a sample vector in matlab it would look like
vec1 = X(x1, y1, z1, :)
vec2 = X( x2, y2, z2, :)
this would give you all values (I have 300 of them) corresponding to this
(x1,y1,z1) point of X.
Now I read the MATLAB datafile 4D

help with interpreting what nnet() output gives:
...3 columns are x,y,z
coordinates. And I need all values in the last column correcponding to a
given (x,y,z) coordinate.
if you list the values of X, then they are non zero, but for some reason R
tells that dim(X): NULL
