bootstrap subject resampling: resampled subject codes surface as list/vector indices
I'm implementing a custom bootstrap resampling procedure in R. This
procedure resamples clusters of data points obtained by different
subjects in an experiment. Since the bootstrap samples need to have the
same size as the original dataset, `target.set.size`, I select speakers
compute their data point contributions to make sure I have a set of the
right size.

target.sample.size = 1742

summarizing matrix data
Hi everyone,
I'm sure this is simple, but I can't seem to figure this out.
Situation. 3 different groups of subjects each submit n X n matrices of
scores. What I want to do is aggregate each group of scores into a summary
n X n matrix. I need the result to be a matrix so that I can calculate a
dissimilarity structure on it. So I thought I would create a
multi-dimensional array and store the data that way.

How to speed up or avoid the for-loops in this example?
...ctors and those parts
all run very quickly indeed. I spent quite a while doing searches on

I have copied for following table from an article on "Using confidence

I rearranged the data this way:
