Usage
read.aa(file, format = "interleaved", skip = 0, nlines = 0,
  comment.char = "#", seq.names = NULL)
Arguments
file

a file name specified by either a variable of mode character, or a double-quoted string.

format

skip

the number of lines of the input file to skip before beginning to read data.

nlines

the number of lines to be read (by default the file is read until its end).

comment.char

a single character, the remaining of the line after this character is ignored.
