Usage

write.dna(x, file = "", format = "interleaved", append = FALSE)

Arguments

x a list a DNA sequences each made of a single vector of mode character where each element is a nucleotide.
file a file name specified by either a variable of mode character, or a double-quoted string; if file = ""(the default) then the tree is written on the standard output connection.
format a character string specifying the format of the DNA sequences. Two choices are possible: "interleaved" or "sequential".
