Look at congruify.phylo in geiger (and the associated paper: Eastman JM, LJ Harmon, and DC Tank. 2013. Congruification: support for time scaling large phylogenetic trees. Methods in Ecology and Evolution).
You could also look into SDM in ape (converting trees [not data] to distance matrices, first): relevant paper Criscuolo, A., Berry, V., Douzery, E. J. P. , and Gascuel, O. (2006) SDM: A fast distance-based approach for (super)tree building in phylogenomics. Systematic Biology, 55, 740–755.
