Hi,


I'm a beginner with R.


I have two different  tables with
the variable name dmr1 and tp2 a given following. v1 is the common  column  field of
the both tables. In the first table column v3 is always v2+1 while in
the second table v2 and v3 hold the range. I want to know which rows
of tb1 intersect with the range between v2 and v3 of tb3. I need some one's kind help to solve this problem.






dmr1<

v1    v2    	v3    	v4

"a"  	22   	23     3

"a"   36    37     1

"a"  	54   	55     0

"a"  	77   	78     1

"b"  	80   	81     4

"b"  	85    86     0

"b"  	99   100    1

"b" 	105  106    0

"b" 	120 	121    1

"b" 	130 	131    1

"b" 	140 	141   	0

"b" 	150  151   	5

"c" 	172 	173   	0

"c" 	177 	178   	1

"c" 	190 	191   	6

"c"  200 	201   	8

"c"  220 	221   	0

"c" 	300 	301   	9

"c" 	310 	311  	10

---------------------------------

tp2<

v1      v2      	v3

"a"    	20     	40

"a"    	70     	80

"b"     	90   	110

"b"    	130   	140

"c"    	190   	230
