[R] write.csv to text string?

[Sarah Goslee]

It's really not a job for the write.* functions, but for the
string-handling functions.

Here's a slightly clunky possibility:

# use your example
s.df <- read.csv(text='cola,colb\n1,2\n2,3\n')

# turn a data frame into a string
paste(
   paste(colnames(s.df), collapse=","),
   paste(apply(s.df, 1, paste, collapse=","), collapse="\n"),
   sep="\n")
