[R] Formatting summary() output to a file

[William Dunlap]

I often use capture.output to slightly reformat printout output.  E.g, to
indent str's output to make it easier to read debugging printouts:
debug_print <- function(x, name=substitute(x), indent=4)
{
   cat(sep="\n", name, paste0(strrep(" ", indent), capture.output(str(x))))
}
Used as in
> myData <- list(One=1:100,Two=log2(1:5))
> debug_print(myData)
myData
    List of 2
     $ One: int [1:100] 1 2 3 4 5 6 7 8 9 10 ...
     $ Two: num [1:5] 0 1 1.58 2 2.32
