Matrices generally don't keep the names of elements assigned to them.
What you did is similar to
x <- matrix(0, 2,2)
x[1,1] <- c(G=2)
which loses the name.
Working with lists is different, because you need to distinguish between
subsets and elements. So you'd get what you want by assigning your list
to the element using
TunePar[[1,1]] <- list(G=2)
At this point, TunePar[1,1] is a list containing list(G=2): it prints as
To get the result you want, you also need to access the element instead
of the subset: TunePar[[1,1]] will print
