Re: [R] print.data.frame to string?
It will work if you paste a "\n" to the end of each line:
a <- data.frame(x=runif(4), y=runif(4), z=runif(4))
b <- capture.output(a)
c <- paste(b, "\n", sep="")
cat("Your data set is:\n", c, "\n")

Re: [R] print.data.frame to string?
thanks, jeff. no, not capture.output(), but thanks for pointing me to it
(I did not know it). capture.output flattens the data frame. I want the
print.data.frame output, so that I can feed it to cat, and get reasonable
newlines, too.

Re: [R] print.data.frame to string?
capture.output(print(mydf))
note that df is a base function... best to not use it as a variable.

Re: [R] print.data.frame to string?
What do you mean by prints? You can use capture.output to get what
would regularly be printed to the screen into a text vector, or use
dput to get a version of an object that could be read back into
another R session.

[R] print.data.frame to string?
dear R experts---is there a function that prints a data frame to a string?
cat() cannot handle lists, so I cannot write cat("your data frame is:\n",
df, "\n").
