R help - Jun 2010 - Help R

Hello,
       I'm new in using the R, but from what I read is an excellent tool.
      Would you like if I could help, I am trying create an array from reading
   a text file.
      The idea is to read the file, and transform the data in binary format,
   for example. The calves of this file format.
   A,B,C,D,G
   A,C,E,O
   F,G
   Put this away
      a b c d e f g o
   1  1 1 1 1 0 0 1 0
   2  1 0 1 0 1 0 0 1
   3  0 0 0 0 0 1 0 0
    and display in monitor.
     Thanks for the help

Try this:

Lines <- "A,B,C,D,G
A,C,E,O
F,G"

x <- read.table(textConnection(Lines), sep = ",", fill = TRUE,
colClasses rep('character', 3))
xtabs( ~ r + values, transform(stack(x), r = rownames(x)))
