print.data.frame to string?
6 messages · Greg Snow, Jeff Newmiller, David L Carlson +1 more
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.

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").

capture.output(print(mydf))
note that df is a base function... best to not use it as a variable.

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")

I want the print.data.frame output, so that I can feed it to cat, and get reasonable newlines, too. regards, /iaw ---- Ivo Welch (ivo.welch at gmail.com) J.
