Multiple records with same name

[mwpennell]

When a vector contains multiple species with the same name, diversitree uses only the first observation. The correct behavior should be to throw an error. I just corrected this in geiger
mwpennell/geiger-v2@b7a7d45

MWE

library(diversitree)

## simulate a continuous dataset
set.seed(1)
t <- tree.bd(c(1,0), max.taxa=10)
d <- sim.character(t,1)

## using the simulated dataset
lik <- make.bm(t,d)
lik(1)

## adding a species with same name to data
d2 <- c(d, "sp10"=1)
lik2 <- make.bm(t,d2)

## likelihood is the same
lik2(1)

## however, swapping order of species
d3 <- d2[c(1:9,11,10)]
lik3 <- make.bm(t,d3)

## different likelihood
lik3(1)

Thanks Matt!

Possible fix following same type of bug in geiger: mwpennell/geiger-v2@b7a7d45
