[R] write.csv to text string?

[Thomas Nyberg]

(Forgot to CC my response to the list...)

Thanks a lot this is exactly what I'm looking for! This is how I'll
probably use it...

----------------
> a
  cola colb
1    1    2
2    2    3

> f <- textConnection("s_a", "w")

> write.csv(a, f, row.names=F)

> close(f)

# Next do something with s_a...though probably not the following which #
is pointless.

> s_a
[1] "\"cola\",\"colb\"" "1,2"               "2,3"

> read.csv(text=s_a)
  cola colb
1    1    2
2    2    3
----------------

Thanks again everyone!

Cheers,
Thomas
