Hi, I am looking to import .nexus file in R to analyze it but am facing errors in the import step itself. I tried the following commands and obtained the following error messages.
> file<-read.nexus("hominoid.nex")
Error in start:end : NA/NaN argument
>tree<-read.tree("hominoid_apriori.tre")
Error in if (tp[3] != "") obj$node.label <- tp[3] :
missing value where TRUE/FALSE needed
> file2<-read.nexus("testmodel.nex")
Error in X[sb] <- gsub(".*\\]", "", X[sb]) :
NAs are not allowed in subscripted assignments
In addition: Warning messages:
1: In grep("\\[", X) : input string 26 is invalid in this locale
2: In grep("\\[", X) : input string 231 is invalid in this locale
3: In grep("\\]", X) : input string 26 is invalid in this locale
4: In grep("\\]", X) : input string 231 is invalid in this locale
5: In LEFT == RIGHT :
longer object length is not a multiple of shorter object length
The file link,

I will be glad to provide necessary details, kindly advice.
PS: I am able to read the file using read.csv
command but not able to perform any operations with it.

Thank you for your clarification and suggestion. I understand the files are PAUP files, but my orders are specific to analyze them using R and PhyML.
I am able to import to the file into R-studio but can you help me understand what it means and how I should proceed. I tried to outgroup "Lemur_catta" but I get the message stating
I had used the root command from http://svitsrv25.epfl.ch/R-doc/library/ape/html/root.html
Can you guide me on this, I appreciate any help you could provide me with.
BR, M
I want to make sure that different questions made up as new posts so other people who need help don't have to dig through things. Could you submit this as a new question and provide a bit more detail (i.e., which file you are trying to load, what exactly you want to do, etc.)? I'm guessing you want to get a ML tree and analyze it in some fashion.
Edit: you could provide a link to the question as a comment or tag it with 'Phylogenetics' - either way I'll be able to find it.
