Diane, As I answered on the geomorph.google group, the package geomorph does not have a 'bilateral missing' function. The 'estimate.missing' function allows either TPS-based or regression-based landmark estimation.
For bilateral options, one could see functions in the package LOST or Morpho packages. Dean Dr. Dean C.

Most of the collections from this period are incomplete due to important fragmentagtion -only the temporal region is rather well preserved. Moreover, temporals are isolated from their cranium, both temporals are seldom present and to my knowledge without midline landmarks it is impossible to estimate the symetry. I was thinking about using a complete skull (same sex and geographic origin) and « merging » the temporal I have with it to estimate the other side or specific landmarks using missing bilateral function from the Rgeomorph package. Are there any other options, or a function that can estimate missing bilateral landmark (knowing that the temporals are not completly symetrical)?
