Hi shaqifahsani,
This is almost certainly due to missing values in the final data 
structure "p_treePhone.phylo" (which may have propagated from missing 
values in the original data frame). I think that p_treePhone.phylo will 
probably have "x" and "y" components. You can see the structure with:

str(p_treePhone.phylo)

If there is a "$x" component, look at it with:

p_treePhone$x

If there are any NA or NaN or Inf values, this is your problem. You may 
be able to get around it with the "complete.cases" function.
