Hi Torvon, In R you can specify rownames and columnames to a matrix, which in essence becomes what you describe as first row and first column, except they are not actually rows or columns (so that the matrix is still numeric). qgraph will extract labels from these rownames. You can also use the labels argument in qgraph to give a vector with a label for each variable.
