Hello,

I'm a new R user.

I have two different dummy tables with the variable name tb1 and tb2.


 tb1<

v1        v2     v3     v4

"chr1"   22    23     3

"chr1"   36    37     1

"chr1"   54    55     0

"chr1"   77    78     1

"chr2"   80    81     4

"chr2"   85    86     0

"chr2"   99   100    1

"chr2"  105  106    0

"chr2"  120  121    1

"chr2"  130  131    1

"chr2"  140  141    0

"chr2"  150  151    5

"chr3"  172  173    0

"chr3"  177  178    1

"chr3"  190  191    6

"chr3"  200  201    8

"chr3"  220  221    0

"chr3"  300  301    9

"chr3"  310  311   10

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

tb2<

v1           v2       v3

"chr1"     20      40

"chr1"     70      80

"chr2"      90    110

"chr2"     130    140

"chr3"     190    230



 The first column is the common 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 intercept with the range between v2 and v3
of tb3. I tried but I failed to solve the problem.

Could anyone help me please?


 Thanks in advance.
