Dear "R" users,

I have a question about the Package DierckxSpline. I have tried to find the answer by myself but it didn't worked out.

I wondered if Dierckxspline can use different sets of y values in one time to fit a line with knot. I have different sets of Y values representing the same thing for different voxels (in an fmri image). I have already fitted the data in different graphs and I know now that the plots are comparable for the different data sets (so for the different voxels) but I wanted to include all the information in one plot, If it's possible. So I want to know the best fitting line for the whole cluster of voxels except for one voxel.
If there is no possibility to do this I tought it would be an option to take the mean of the different y-values and use those values but I don't know if this is mathematical right to do.
I hope someone can help me with this.

Thank you very much,
