embedding data frame in R code?

and you probably want closeAllConnections() immediately following
No you do not want to close all connections.  You should close each
connection that you open, but not others (they may be used by other
functions like sink() or capture.output()).  Use something like:

   readTableFromText <-function (text, ...) {
       tc <- textConnection(text, open = "r")
       on.exit(close(tc))
       read.table(tc, ...)
   }

as in

   > readTableFromText(c("10 ant", "20 bear", "30 cougar"), row.names=NULL)
     V1     V2
   1 10    ant
   2 20   bear
  3 30 cougar
  > showConnections() # no open connections
        description class mode text isopen can read can write

I'm not sure I entirely understand the question, but the closest thing
I can think of to a data frame literal, excepting dput(), would be
this:

d <- read.csv(textConnection("
a, b
1, cow
2, dog
3, cat"), header = TRUE)

and you probably want closeAllConnections() immediately following to
avoid a warning.

Best,
Michael

I would like to insert a few modest size data frames directly into my
R code.  a short illustration example of what I want is

d <- read.csv(  _END_, row.names=1  )
 , "col1", "col2"
"row1",1,2
"row2",3,4
__END__

right now, the data sits in external files.  I could put each column
into its own vector and then combine into a data frame, but this seems
ugly.  is there a better way to embed data frames?  I searched for the
answer via google, but could not find it.  it wasn't obvious in the
data import/export guide.
