center() fails when .data doesn't have rownames

[mikemc]

I think center() should be able to handle this case; rows correspond to samples and there is no need for the samples to have names for computing the center to make sense. Note, the function works fine w/o column names if enframe is not used.

Z <- matrix(c(
        NaN, 1, 3.5, 
        -1, NaN, 4,
        -2, 3, NaN,
        -1, 2, 3), ncol = 3, byrow = T)
# colnames(Z) <- paste0("T", 1:3)
# rownames(Z) <- paste0("S", 1:4)
metacal::center(Z, in_scale = "log")
#> Object passed to `as_tibble()` must have row names if the `rownames`
#> argument is set.

The problem is arising within coocurrence_matrix(). In particular, the call to tibble::as_tibble(mat, rownames = "Sample").
