strip leading 0's
Thanks for the suggestion replacing the leading 0 with a space instead of nothing to preserve the layout, and for explaining why there is no option for this. Yes, I see why this sounds like a bad idea. The reason I asked is that I use Sweave to write statistical reports, and I like to get the formatting as close as possible without editing the .tex file afterward. In my field (psychology) it is standard practice to omit the leading zeros when reporting statistics whose value cannot exceed 1, mainly correlations and p values.

The only comprehensive way to do this would be to change R's internaal print mechanisms. (Note that changing 0. to . breaks the layout: changing '0.' to ' .' would be better.) But you haven't told use why you would want to do this. Leaving off leading zeroes makes output harder to read for most people, and indded leading periods are easy to miss (much easier than failing to see that you were asked not to send HTML mail). It would be easy for the cognescenti to add an option to R, but I suspect they all would need a lot of convincing to do so. On Sat, 24 Jan 2009, Ista Zahn wrote:
Dear all,
Is there a simple way to strip the leading "0"'s from R output? For example,
I want
Data <- data.frame(x=rnorm(10), y=x*rnorm(10), z = x+y+rnorm(10))
cor(Data)
to give me
x y z
x 1.0000000 -.1038904 -.3737842
y -.1038904 1.0000000 .4414706
z -.3737842 .4414706 1.0000000
Several of you were kind enough to alert me to the existence of gsub a few
weeks ago, so I can do
gsub("0\\.","\\.",cor(Data))
but I'm hoping someone has a better way (e.g, one that returns an object of
the same class as the original, preserving dimnames, etc.)
Thanks,
Ista
