Usage

  tree.load.data(phylo, x, ...)

Arguments

phylo	input phylo object
x	input data.frame or string indicating the location of a CSV file.

Value

the phylo object, with tags corresponding to the data from the input dataset.

Examples

tree <- tree.read('((a,b)c,d)e;')
x <- data.frame(
  label=c('a', 'b', 'c', 'd', 'e'),
  value=c(1, 2, 3, 4, 5)
)
tree <- tree.load.data(tree, x)
print(as.character(tree)) # as NHX string
print(as.data.frame(tree, minimal.columns=TRUE)) # as data.frame
