[R] Data manipulation query

[Manoj - Hachibushu Capital]

Hi,
	Not sure if I am making a simple problem complex but still here
we go:

	I have a data frame with four columns say, X1 X2 X3 and X4. I
want to break X4 into deciles and for each deciles obtained, I want to
see corresponding elements of X1. 

	Ideally, the output should be in a tabular fashion as shown
below:

	Deciles 1 Deciles 2	....	Deciles 10

	X1-1	   X1-2		 X1-99
	X1-5	   X1-3		
	X1-10

	Where X1-1...X1-100 are elements of column X1 that categorized
as per deciles

	Any pointers to help get the right structure would be greatly
appreciated!!

TIA.
