I'm using phyl.pairedttest for a forthcoming paper; very cool application and was working fantastic with the species means alone, but when I incorporated standard.errors for my means I'm getting an error message:
Error in solve.default(V, d - dbar) :
Lapack routine dgesv: system is exactly singular: U[5,5] = 0
All my traits give this error so it is not an oddity of a particular trait. The tree is small (9 tips) but nothing odd about it (no zero-length branches).
Let me know if you have any suggestions to explore or want me to send you the data so you can recreate the error.
