[R] output without labels and delimited by Tab

[ben@zoo.ufl.edu]

  The main function driving the formatting here is summary.data.frame().
You can hack this function to get the formatting you want.

  Or (for a probably-quicker but less general solution) you can just write
your own function with less complication than summary.data.frame.

mysum <- function(x) {
  qq <- quantile(x,c(0.25,0.5,0.75))
  c(min(x),qq[1:2],mean(x),qq[3],max(x))
}

write.table(apply(x,2,mysum),sep="\t",quote=FALSE,row.names=FALSE)

Does more or less what you want, although there is a problem with the
column headers being shorter (and thus not tabbed over as far) as the
columns.  You could implement something with blank-padding, keeping the
same number of significant digits for all the numbers, etc., but
eventually you will find yourself rewriting summary.data.frame() from
scratch.
