Help with MuSSE csv file

[LiliyaSerbina]

Hi everyone!

I am struggling with a constant problem with a csv extension while preparing data for MuSSE model analysis: have tried to do a bunch of stuff to fix a problem but no success - always the same thing ("All names must be length 1"). I would very grateful for your help! :)

library(diversitree)
dat="MuSSE_hosts.csv"
dat<- read.table("MuSSE_hosts.csv", header=TRUE, dec=".", sep=",", row.names=1)
mat <- dat[,2:ncol(dat)]
lik.0 <- make.musse.multitrait(tree, mat, depth=0)
Error in check.states.musse.multitrait(tree, states, strict = strict, :
All names must be length 1
