[R] Simple question on replace a matrix row

[anna]

David, I think I am going close to the problem, at the end of the function
ComputeSignalReturns I build the matrix summary with cbind. So when I make
class(summary) I get "matrix" but when I make class(summary[1,]) I get
"list"
Excuse me if I didn't show the problem the right way, I am still new and I
am trying to do my best
Here is one output of ComputeSignalReturns(summary):
                       A                   B               C                     
D               E       F     G
