Hi all,
I have a matrix of correlation values between all pairwise comparison in
an experiment. For example, I have 2 time points (1,2) each in
triplicate. Thus, I have the following matrix
1-1
1-2
1-3
2-1
2-2
2-3
1-1
NA
...
...
...
...
...
1-2
...
NA
...
...
...
...
1-3
...
...
NA
...
...
...
2-1
...
...
...
NA
...
...
2-2
...
...
...
...
NA
...
2-3
...
...
...
...
...
NA
What I'd like to do is to reshape the data so that it would be easy for
me to summarize all the correlation values across the triplicates (i.e.
mean) for time point 1 and 2. It sounds as though the reshape package
should be able to do this, but the solution is not obvious to me. Can
anybody help?
Best,
Ken
