I believe so. > str(hc) List of 7 $ merge : int [1:15, 1:2] -6 -13 -10 -1 -9 -3 -5 -16 -12 8 ... $ height : num [1:15] 20.1 23.6 27.2 29.2 41.4 ... $ order : int [1:16] 1 2 3 4 16 13 14 12 15 5 ... $ labels : chr [1:16] "1947" "1948" "1949" "1950" ... $ method : chr "average" $ call : language hclust(d = dist(data.matrix(longley)), method = "ave") $ dist.method: chr "euclidean" - attr(*, "class")= chr "hclust" so the "merge" component is a n x 2 matrix, whose mode is "numeric".
