I thought about that star graph again, and realized that it would be quite

Dear Aedin,
Similar questions have been asked quite often on this list.
See FAQ 7.25, the manual An Introduction to R, and the online
help, especially ?merge, ?sort, ?order, and ?data.frame.

Hey, R-listers,
Given the observed N random scalar variable x, with
zero mean and unit variance, can we separate the
two independent component x1 and x2 such that
x = x1 + x2 (x1 and x2 are assumed to be zero mean)?
Maybe there is no way to figure it out, and just
wanna get some help and try it.
Dear Fred,
If x1 and x2 are *not* normally distributed, you can use
independent component analysis (ICA) which is based on the
idea that x will be more normal than either x1 and x2
following the central limit theorem. See package(fastICA)
by JL Marchini, C Heaton, and BD Ripley for details.

Hello,
I am running R 1.7.1 on two platforms and it seems to me that order() behaves
differently on them. I noticed this when a test case passed in linux but
failed on solaris. This is the behavior on the solaris platform:
